EXPERIMENT #4
GREEN LEWIS ACID-CATALYZED HYDROLYSIS OF CYCLOHEXENE OXIDE
Introduction:
Epoxides are three-membered ethers. They are special because unlike most ethers, they can react
with nucleophiles to form a new bond between carbon and the nucleophile and break a bond
between that carbon and oxygen. This ring-opening reaction makes epoxides versatile functional
groups for organic synthesis. (In fact epoxide is the functional group that makes epoxy resins
possible.)
Scheme 1. Ring opening of an epoxide in the presence of a nucleophile.
Ring-opening of the epoxide can occur under basic or acidic conditions. Under basic conditions,
the reaction is similar to an SN2 reaction so that the nucleophile attacks the less substituted carbon
of an unsymmetrical epoxide by backside attack. Sodium ethoxide reacts with this epoxide in the
following reaction.
Scheme 2. Ring opening of an unsymmetrical epoxide under basic conditions.
Under acidic conditions, the reaction is more complicated. It is similar to an SN2 reaction because
the nucleophile reacts by backside attack. However, because there is partial positive charge on the

Water Testing Lab
Background Information:
Chemists can detect and identify ions in water solution in several different ways. In this lab you will use
some chemical tests to check for the presence of certain ions in aqueous solution. Positively charged
ions are called cations; negatively charged ions are called anions. The tests you will perform are
confirming tests. If the test is positive, it confirms that the ion in question is present. In each confirming
test you will look for a change in solution color, or the appearance of an insoluble material called a
precipitate. A negative test (no color change or precipitate) doesn’t necessarily mean the ion in
question is not present. The ion may simply be present in such a small amount that the color or
precipitate cannot be seen.
Purpose:
§ To use chemical tests to determine the presence of ions in three different water samples.
Objectives:
§ To test for the presence of cations iron (III) Fe3+, calcium Ca2+, copper Cu+, as well as the
anions chloride Cl-, phosphate PO43-, and sulfate SO42-.
§ To perform each of the following confirming tests on three different samples:
1. A reference solution (known to contain the ion of interest)
2. Tap water (which may or may not contain the ion)
3. A control (distilled water, known not to contain the ion)
§ Test for water hardness using ion-testing strips.
§ Complete a confirmative ion-testing using a complete ion-testing strip.
Materials:
§ 10 test tubes
§ Test tube rack
§ 10 mL graduated cylinder
§ Test reagent solutions in dropper bottles
o Potassium thiocyanate (KSCN)
o Potassium oxalate (K2C2O4)
o Acetic acid (HC2H3O2)
o Silver nitrate (AgNO3)
o Barium Chloride (BaCl2)
§ Reference ion solutions
o Iron (III) Nitrate - Fe(NO3)3
o Calcium Chloride – CaCl2

Please response to these two original posts below. When
responding to these posts, please either expand the
thought, add additional insights, or respectfully disagree
and explain why. Remember that we are after reasons
and arguments, and not simply the statement of
opinions.
Original Post 1
Are human lives intrinsically valuable? If so, in virtue of what? (Is
it our uniqueness, perhaps, or our autonomy, or something else?)
To begin, I would like to remind us that being intrinsically valuable
means having values for just being us and nothing else. I believe
that human lives are intrinsically valuable in virtue of our
uniqueness. As a bio nerd, I would like to state the fact that there
are a lot of crossover events during meiosis, which create trillions
of different DNA combinations. Hence, from a biological
standpoint, without considering other aspects, being you is
already valuable because you are that one sperm that won the
race and got fertilized. On a larger scale, there are hardly two
people whose look and behaviors are the same in the same
family, unless they are identical twins. However, identical twins
still act differently and have differences (such as fingerprints).
Since we are raised in different families, we are taught different
things and have different cultures. In general, we all have
different genetic information, appearances, personalities, senses
of humor, ambitions, talents, interests and life experiences. These
characteristics make up our “unique individual value” and make
us so unique and irreplaceable.
I would also love to discuss how our diversities enrich and
contribute to society, but that would be a talk about our extrinsic
values.
Original Post 2
Are human lives intrinsically valuable? If so, in virtue of what? (Is
it our uniqueness, perhaps, or our autonomy, or something else?)
I believe that human lives are intrinsically valuable due to a
number of reasons. Firstly, human lives aren’t replaceable. You
can’t replace a human being with another just like you can
replace a broken laptop with brand new one. Part of the reason
why we tend to think this way is that we were nurtured with the

Part C Developing Your Design
Solution
The Production Cycle
Within the four stages of the design workflow there are two distinct parts.
The first three stages, as presented in Part B of this book, were described
as ‘The Hidden Thinking’ stages, as they are concerned with undertaking
the crucial behind-the-scenes preparatory work. You may have completed
them in terms of working through the book’s contents, but in visualisation
projects they will continue to command your attention, even if that is
reduced to a background concern.
You have now reached the second distinct part of the workflow which
involves developing your design solution. This stage follows a production
cycle, commencing with rationalising design ideas and moving through to
the development of a final solution.
The term cycle is appropriate to describe this stage as there are many loops
of iteration as you evolve rapidly between conceptual, practical and
technical thinking. The inevitability of this iterative cycle is, in large part,
again due to the nature of this pursuit being more about optimisation rather
than an expectation of achieving that elusive notion of perfection. Trade-
offs, compromises, and restrictions are omnipresent as you juggle ambition
and necessary pragmatism.
How you undertake this stage will differ considerably depending on the
nature of your task. The creation of a relatively simple, single chart to be
slotted into a report probably will not require the same rigour of a formal
production cycle that the development of a vast interactive visualisation to
be used by the public would demand. This is merely an outline of the most
you will need to do – you should edit, adapt and participate the steps to fit
with your context.
There are several discrete steps involved in this production cycle:
Conceiving ideas across the five layers of visualisation design.
Wireframing and storyboarding designs.
Developing prototypes or mock-up versions.
219
Testing.
Refining and completing.
Launching the solution.
Naturally, the specific approach for developing your design solution (from
prototyping through to launching) will vary hugely, depending particularly
on your skills and resources: it might be an Excel chart, or a Tableau
dashboard, an infographic created using Adobe Illustrator, or a web-based
interactive built with the D3.js library. As I have explained in the book’s
introduction, I’m not going to attempt to cover the myriad ways of
implementing a solution; that would be impossible to achieve as each task
and tool would require different instructions.
For the scope of this book, I am focusing on taking you through the first
two steps of this cycle – conceiving ideas and wireframing/storyboarding.
There are parallels here with the distinctions between architecture (design)
and engineering (execution) – I’m effectively chaperoning you through to
the conclusion of your design thinking.

Implications to Nursing Practice & Patient Outcomes
Nurses need to know that they play a significant role in the reduction of hospital acquired infection by ensuring by health care workers and patients wash hands since nurses have the most interactions with patients. Implementing hand hygiene protocol with patients can enhance awareness and decrease healthcare associated infection (HAI). Both nurses and patients need to know that HAI is associated with increased morbidity and mortality as well cost of treatment and length of hospital stay. Nurses and patients also need to know that most HAI is preventable. Gujral (2015) notes that proper hand hygiene is the single most important, simplest, and least expensive means of reducing prevalence of HAI and the spread of antimicrobial resistance. Nurse and patient hand washing plays a vital role in decreasing healthcare costs and infections in all settings.

PART AHepatitis C is a chronic liver infection that can be e.docxsmile790243
PART A
Hepatitis C is a chronic liver infection that can be either silent (with no noticeable symptoms) or debilitating. Either way, 80% of infected persons experience continuing liver destruction. Chronic hepatitis C infection is the leading cause of liver transplants in the United States. The virus that causes it is blood borne, and therefore patients who undergo frequent procedures involving transfer of blood are particularly susceptible to infection. Kidney dialysis patients belong to this group. In 2008, a for-profit hemodialysis facility in New York was shut down after nine of its patients were confirmed as having become infected with hepatitis C while undergoing hemodialysis treatments there between 2001 and 2008.
When the investigation was conducted in 2008, investigators found that 20 of the facility’s 162 patients had been documented with hepatitis C infection at the time they began their association with the clinic. All the current patients were then offered hepatitis C testing, to determine how many had acquired hepatitis C during the time they were receiving treatment at the clinic. They were considered positive if enzyme-linked immunosorbent assay (ELISA) tests showed the presence of antibodies to the hepatitis C virus.
Health officials did not test the workers at the hemodialysis facility for hepatitis C because they did not view them as likely sources of the nine new infections. Why not?
Why do you think patients were tested for antibody to the virus instead of for the presence of the virus itself?

PART B
Please response to these two original posts below. When responding to
these posts, please either expand the thought, add additional insights, or
respectfully disagree and explain why. Remember that we are after reasons
and arguments, and not simply the statement of opinions.
Original Post 1
"What is moral relativism? Why might people be attracted to it? Is
it plausible?"
First of all, moral relativism is the view that moral truths are
subjective and depend on each individual's standpoints. Based
on this, everyone's moral view is legitimate. This can be attracted
because it sounds liberating and there is no need to argue for a
particular position. Moral relativism seems convincing in some
cases. For example, some people are okay with giving money to
homeless people, thinking that it's good to provide for the people
in need. Some people, on the other hand, claim that they can
work to satisfy their own needs. Moral relativism works well in
these cases because they all seem legitimate. However, there are
cases that moral relativism does not seem reasonable. For
example, child sacrifice in some cultures seems cruel and
uncivilized to most people. Hence, moral relativism is not
absolutely true.
Original Post 2
“Is your death bad for you, specifically, or only (at most) for others? Why
might someone claim that it isn’t bad for you?”
I'd start off by acknowledging what the two ancient philosophers,
Lucretius and Epicurus, outlined about death. They made the
point that death isn't necessarily bad for you since no suffering
takes place and that you yourself don't realize your own death. In
this way, one could make the claim that death isn't intrinsically
bad for you.
Another perspective I wanted to add was the influence of death
(both on you and others around you). Specifically, the event of
death itself may not be bad for you, but the idea of impending
death could impact one's life. Some may live freely, totally care-
free, accepting of death and enjoy life in the moment. Others may
be frightened by the idea of death that they live in constant fear
and hence death causing their mental health to take its toll. In
this way, I'd argue that death could, in fact, be bad for you. One
common reason for being afraid of death is the fear of being
forgotten. Not to mention the death of an individual certainly
affects others; death doesn't affect one's life but also all that is
connected to it. Focusing back to the point, it's clear that the
very idea of death directly affects the concerned individual. The
fact that those who live in fear of death are looking for legacies
and footprints to leave after they leave this world is telling of how
death could be arguably bad for you before it even happens.

A. UTI is short form for Urinary tract infection. Means infection which affects organs of urinary tract. Such as urethra, urinary bladder and kidney. This are main organ for formation of urine and helps to expel it out of body.
B. Kidneys, urethra and urinary bladder gets affected during Urinary tract infection. Generally infection begins with urethra then travels to kidney.
When only lower part gets affected which is called lower UTI also cystitis because involves bladder
And when infection spread to upper side involving kidneys known as pyelonephritis.
2.
A. Microorganism in UTI
Escherichia coli
Klebsiella pneumoniae
B. Coli bacteria lives in intestine. So they also seen near anal canal. From which gets transferred to urethra.
C. Bacteria enters urinary tract from urethra. In very less cases kidney gets infected by blood stream.
3.
Signs and symptoms:
A) Pain with urination:
The infection cause inflammation of urinary tract, the urine from the inflammed urinary tract cause pain in urination.
B) orange or red colour urine:
The inflammation of urinary tract may cause a orange or red colour urine. It is common sign in UTI due to inflammation of urinary tract.
4.
UTI:
Urinary tract infection (UTI) any infection on the urinary tract causing difficult in urination. It most commonly affects the woman because thet are more prone to it.
Diagnosis And treatment:
A) The diagnostic test for UTI:
The two major diagnostic test for UTI are:
Urinalysis:
Urine is collected from the patient who came for test. This test shows the bacterial or any infectious organism in the urine.
The collected urine sample is added to the substance which promotes the growth of the organism in the urine.
If the growth is organism doesn't takes place then the test is negative.
If the organism growth in the urine takes place then the test is positive.
Ultra sound:
The sound waves from the transducer of ultra produce a imaging of the internal organs.
Patient lower abdomen is scanned by ultra sound to detect any abnormality in the organs and structures of urinary tract.
B) The medications for UTI are antibiotics or antimicrobial.
The two drugs are amoxicillin, sulfasulfamethaxazole.
Both of these drugs act on UTI by fighting against the microorganisms in the UTI. By assisting the immune system, it fight against the microorganisms and that relieves the symptoms of UTI.
5.
answer. a) In women at the time of pregnancy the drainage system from the kidney towards bladder become wide, hence, urine does not pass out as quickly. This makes it easier to get an infection. Similarly women has shorter urethra than a man have, the shorter distance make the way easy to bacteria to travel into the bladder.
b) There are no of ways by which women can reduce the risk of getting UTI. Like women should drink plenty of water this will help of getting rid from UTI, a women should protect their urethra .

Are human lives intrinsically valuable? If so, in virtue of what? (Is
it our uniqueness, perhaps, or our autonomy, or something else?)
To begin, I would like to remind us that being intrinsically valuable
means having values for just being us and nothing else. I believe
that human lives are intrinsically valuable in virtue of our
uniqueness. As a bio nerd, I would like to state the fact that there
are a lot of crossover events during meiosis, which create trillions
of different DNA combinations. Hence, from a biological
standpoint, without considering other aspects, being you is
already valuable because you are that one sperm that won the
race and got fertilized. On a larger scale, there are hardly two
people whose look and behaviors are the same in the same
family, unless they are identical twins. However, identical twins
still act differently and have differences (such as fingerprints).
Since we are raised in different families, we are taught different
things and have different cultures. In general, we all have
different genetic information, appearances, personalities, senses
of humor, ambitions, talents, interests and life experiences. These
characteristics make up our “unique individual value” and make
us so unique and irreplaceable.
I would also love to discuss how our diversities enrich and
contribute to society, but that would be a talk about our extrinsic
values.

I believe that human lives are intrinsically valuable due to a
number of reasons. Firstly, human lives aren’t replaceable. You
can’t replace a human being with another just like you can
replace a broken laptop with brand new one. Part of the reason
why we tend to think this way is that we were nurtured with the

PART B
Please response to these two original posts below. When responding to
these posts, please either expand the thought, add additional insights, or
respectfully disagree and explain why. Remember that we are after reasons
and arguments, and not simply the statement of opinions.
Original Post 1
"What is moral relativism? Why might people be attracted to it? Is
it plausible?"
First of all, moral relativism is the view that moral truths are
subjective and depend on each individual's standpoints. Based
on this, everyone's moral view is legitimate. This can be attracted
because it sounds liberating and there is no need to argue for a
particular position. Moral relativism seems convincing in some
cases. For example, some people are okay with giving money to
homeless people, thinking that it's good to provide for the people
in need. Some people, on the other hand, claim that they can
work to satisfy their own needs. Moral relativism works well in
these cases because they all seem legitimate. However, there are
cases that moral relativism does not seem reasonable. For
example, child sacrifice in some cultures seems cruel and
uncivilized to most people. Hence, moral relativism is not
absolutely true.
Original Post 2
“Is your death bad for you, specifically, or only (at most) for others? Why
might someone claim that it isn’t bad for you?”
I'd start off by acknowledging what the two ancient philosophers,
Lucretius and Epicurus, outlined about death. They made the
point that death isn't necessarily bad for you since no suffering
takes place and that you yourself don't realize your own death. In
this way, one could make the claim that death isn't intrinsically
bad for you.
Another perspective I wanted to add was the influence of death
(both on you and others around you). Specifically, the event of
death itself may not be bad for you, but the idea of impending
death could impact one's life. Some may live freely, totally care-
free, accepting of death and enjoy life in the moment. Others may
be frightened by the idea of death that they live in constant fear
and hence death causing their mental health to take its toll. In
this way, I'd argue that death could, in fact, be bad for you. One
common reason for being afraid of death is the fear of being
forgotten. Not to mention the death of an individual certainly
affects others; death doesn't affect one's life but also all that is
connected to it. Focusing back to the point, it's clear that the
very idea of death directly affects the concerned individual. The
fact that those who live in fear of death are looking for legacies
and footprints to leave after they leave this world is telling of how
death could be arguably bad for you before it even happens.

A. UTI is short form for Urinary tract infection. Means infection which affects organs of urinary tract. Such as urethra, urinary bladder and kidney. This are main organ for formation of urine and helps to expel it out of body.
B. Kidneys, urethra and urinary bladder gets affected during Urinary tract infection. Generally infection begins with urethra then travels to kidney.
When only lower part gets affected which is called lower UTI also cystitis because involves bladder
And when infection spread to upper side involving kidneys known as pyelonephritis.
2.
A. Microorganism in UTI
Escherichia coli
Klebsiella pneumoniae
B. Coli bacteria lives in intestine. So they also seen near anal canal. From which gets transferred to urethra.
C. Bacteria enters urinary tract from urethra. In very less cases kidney gets infected by blood stream.
3.
Signs and symptoms:
A) Pain with urination:
The infection cause inflammation of urinary tract, the urine from the inflammed urinary tract cause pain in urination.
B) orange or red colour urine:
The inflammation of urinary tract may cause a orange or red colour urine. It is common sign in UTI due to inflammation of urinary tract.
4.
UTI:
Urinary tract infection (UTI) any infection on the urinary tract causing difficult in urination. It most commonly affects the woman because thet are more prone to it.
Diagnosis And treatment:
A) The diagnostic test for UTI:
The two major diagnostic test for UTI are:
Urinalysis:
Urine is collected from the patient who came for test. This test shows the bacterial or any infectious organism in the urine.
The collected urine sample is added to the substance which promotes the growth of the organism in the urine.
If the growth is organism doesn't takes place then the test is negative.
If the organism growth in the urine takes place then the test is positive.
Ultra sound:
The sound waves from the transducer of ultra produce a imaging of the internal organs.
Patient lower abdomen is scanned by ultra sound to detect any abnormality in the organs and structures of urinary tract.
B) The medications for UTI are antibiotics or antimicrobial.
The two drugs are amoxicillin, sulfasulfamethaxazole.
Both of these drugs act on UTI by fighting against the microorganisms in the UTI. By assisting the immune system, it fight against the microorganisms and that relieves the symptoms of UTI.
5.
answer. a) In women at the time of pregnancy the drainage system from the kidney towards bladder become wide, hence, urine does not pass out as quickly. This makes it easier to get an infection. Similarly women has shorter urethra than a man have, the shorter distance make the way easy to bacteria to travel into the bladder.
b) There are no of ways by which women can reduce the risk of getting UTI. Like women should drink plenty of water this will help of getting rid from UTI, a women should protect their urethra .

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Sistine Chapel. Fresco painting involves most of the types of
chemical reactions you just studied. Listed below are some of
the reactions used in creating a Fresco painting. Identify the
type of chemical reaction used for each step and balance the
chemical equation if needed.
Initially, some sort of heat must be generated. Propane is an
example of a common fuel source used for heating.
C3H8 + O2 → CO2 + H2O
This is a ____________________________________________
reaction.
Next, quicklime (calcium oxide) is made by roasting calcium
carbonate (limestone).
CaCO3 → CaO + CO2
This is a ____________________________________________
reaction.
The quicklime is slaked to form lime plaster.
CaO + H2O → Ca(OH)2
This is a
____________________________________________reaction.
The lime plaster is cured or dried.
Ca(OH)2 + CO2 → Ca(OH)(HCO3)
This is a ____________________________________________
reaction.
This quickly continues to react to form calcium carbonate and
water.

1. Place a test tube in a test tube rack or small beaker.
2. Slightly tilt a test tube and slide a small zinc-coated
(galvanized) washer down the side.
3. Use a 10 mL graduated cylinder to measure out
approximately 2 mL of saturated citric acid and carefully pour it
into the test tube containing the zinc washer.
CAUTION: Citric acid is irritating to the eyes and skin.
4. 4. Observe the reaction for several minutes, and record your
observations in the data table.
5. To clean up, separate the acid solution from the washer by
pouring it into a small beaker while leaving the washer in the
test tube. This is called decanting. Rinse the test tube
containing the washer several times with water and add each
rinse to the beaker.
CAUTION: Do not pour the acid directly down the drain. To
neutralize the acid, add small amounts of baking soda to the
solution in the beaker and stir with a stirring rod.
6. Continue stirring and adding small amounts of baking soda
until gas no longer forms. Pour the liquid down the drain and
throw the washer in the trash.

Zn3(PO4)2 (s)
1. Pour approximately 2 mL of 0.1 M zinc acetate
(Zn(C2H3O2)2) into a clean test tube.
2. Add approximately 2 mL of 0.1 M sodium phosphate tribasic
(Na3PO4) into the test tube.
3. Record your observations before and after the addition of
Na3PO4 in the data table.
4. To clean up, pour the contents of the test tube down the
drain.
Part 5: Decomposition (AB → A + B)
(NH4)2CO3 (s) → NH3 + H2O + CO2 (g)
1. Place a spatula tip full (approximately 0.02 g) of ammonium
carbonate (NH4)2CO3, powder into a test tube.
CAUTION: Do not inhale the strong ammonia odor. Try to work
in well-ventilated area.
2. Light the candle using the butane lighter.
CAUTION: Long hair should be tied up and loose clothing
restrained when around an open flame to prevent fire and burns.
Be sure you are wearing your safety goggles.
5. 3. Use a test tube holder to hold the test tube containing the
ammonium carbonate at a slight angle in the candle flame. Keep
the open end of the tube pointed away from you and other
students. Continue to heat the sample until the reaction is
finished.
Hint: Remember the products of this reaction are all gases.
4. Record your observations in the Data section.
5. Allow the test tube to cool to room temperature before

Lab 8: Chemical Reactions I
Pre-lab Questions
1. Name the chemical that makes up teeth.
2. How does plaque harm teeth?
3. How does fluoride promote dental health?
4. Write two solubility rules that are used in this lab.
Experiment: Battle of the Mouth Rinses
Some mouth rinses contain fluoride, usually in the form of
sodium fluoride, which is soluble in water. In this lab, you will
determine which one of two mouth rinses would be better at
preventing cavities by replacing lost minerals with fluoride.
You will do this by determining which rinse contains fluoride.
Procedure
**Take photographs of your experiment set up and your results.
14. Submit them with your laboratory report.**
1. Label the two test tubes with a permanent marker as A and B.
HINT: Make sure to write down which rinse is A and which is
B.
2. Pour 10 mL of Rinse A into the test tube marked A.
3. Pour 10 mL of Rinse B into the test tube marked B.
HINT: If using the same graduated cylinder to measure your
rinses, wash the cylinders WELL between pours to prevent
cross-contamination.
4. Pour 3 mL of 1 M Ca(C2H3O2)2 solution into each of the test
tubes. Gently stir each test tube with a stir rod to mix. Be sure
to clean your stir rod each time before placing it in a solution.
CAUTION: Mixing should be done gently to prevent glass
breakage and injury.
5. Observe and record initial observations immediately after
adding calcium acetate to the test tubes.
6. Observe the reactions for at least 10 minutes to ensure it is
finished. HINT: A positive test is indicated by a cloudy
appearance of the solution. The precipitate formed can be more
easily seen if the test tube is held up to the light. The
precipitate will eventually settle to the bottom of the test tube.
7. Let the test tubes sit for an hour. After an hour, record final
observations.
8. Record all observations in the Data section.
9. To clean up, you can rinse the small amount of precipitate
down the drain.
Data
· Observations of NaF and Ca(C2H3O2)2 (see sequence of
pictures below)
· Observations of Rinse A and Ca(C2H3O2)2
16. 2. What determines if a bond is polar?
3. List several examples of polar molecules.
4. List several examples of non-polar molecules.
5. What is the rule when using polar and non-polar solvents?
Experiment: Slime Time
Some inks are polar while others are non‐polar. A polar solvent
will pick up polar inks, while a non‐polar solvent will pick up
non‐polar inks. In this lab you will use inks to identify slime
and silly putty as polar or non‐polar. You will also use paper
chromatography to verify the inks are correctly identified as
polar or non‐polar.
Procedure
**Take photographs of your experiment for Parts 1, 2, and 3;
and your results. Submit them with your laboratory report.**
Part 1: Making Slime
1. Weigh out 0.5 g of guar gum into a 250 mL beaker.
2. Measure 50.0 mL of distilled water into a 100 mL graduated
cylinder and pour it into the 250 mL beaker that contains the
17. guar gum.
3. Rapidly stir the mixture with a stirring rod for at least 3
minutes and until the guar gum is dissolved.
4. Measure 4.00 mL of a 4% Borax solution into a 10 mL
graduated cylinder and add it to the guar gum and water.
5. Stir the solution until it becomes slime. This will take a few
minutes. If the slime remains too runny, add an additional 1.0
mL of the 4.0% Borax solution and continue to stir until the
slime is the right consistency.
6. Once you are satisfied with the slime, pour it into your
hands. Be sure not to drop any of it on to the floor.
7. Manipulate the slime in your hands. Write down observations
made about how slime pours, stretches, breaks, etc.
CAUTION: Slime is slippery and if dropped it can make the
work area slick.
8. Place the slime back into the beaker and WASH YOUR
HANDS.
Part 2: Slime and Putty Ink Tests
1. On a piece of notebook paper make one 20-25 mm long mark
of each of the inks you are testing. Space the marks at least one
inch apart. Use a pencil to label each mark with its description.
a. Water soluble inks include those in highlighters and certain
pens.
b. Water insoluble inks include those in permanent
pens/markers, newsprint, and a dry-erase markers.
2. While the inks are drying, select a passage or a picture in the
newspaper to test with the slime.
3. Break off a small piece of slime that is 3 - 5 cm in diameter.
Gently place this piece on top of the newspaper print, and then
carefully pick it up again.
4. Observe and record in Table 1 whether or not the ink was
picked up onto the slime.
5. Break off another small piece of slime. Once the inks from
Step 1 have dried, gently place the slime on top of the first spot
on the notebook paper, and then carefully pick it up. Repeat this
18. for each of the inks. Observe and record which inks were picked
up (dissolved) by the slime in Table 1.
6. Repeat this ink testing two more times for accuracy.
7. Before performing ink tests on silly putty, in the Data
section, hypothesize which inks the silly putty will pick up.
8. Perform ink tests on silly putty in the same manner as above.
Record your results in Table 2
Part 3: Chromatography of Ink Samples
1. Use a pencil or scissors to poke a small hole in the center of
a piece of filter paper (see Figure 4).
2. Spot the filter paper evenly spaced approximately 2 cm from
the small hole with the two insoluble inks and the two soluble
inks that were used in Part 2.
3. Obtain a ½ piece of filter paper. Fold the paper in half
several times so that it makes a narrow wick.
4. Insert the wick into the hole of the spotted paper so that it is
above the top of the filter paper by approximately 2 cm.
5. Fill a 250 mL beaker 3/4 full with water.
6. Set the filter paper on top of the beaker so that the bottom of
the wick is in the water. The paper should hang over the edge
of the beaker with the spotted side up.
7. Allow water to travel until it is approximately 1 cm from the
edge of the filter paper. Remove the filter paper from the
beaker.
8. Observe which inks moved from where they were originally
spotted. Record your observations in Part 3 of the Data section.
