Important Criteria for Rate of Reaction of Alka Seltzer Lab
Title:
Should be descriptive and include the DV and IV
Introduction:
· Observations of Alka Seltzer and water
· What is Alka Seltzer?
· What is produced when Alka Seltzer reacts with water?
· Chemical Equation of the reaction
· Discuss Carbon Dioxide
· What is needed to increase the rate of a chemical reaction?
· Link above information to your hypothesis
(Need to use at least one reference for this section. Your book
will count as a reference this time.)
Materials
· Creat a list of the IV, DV, control variables (need at least 3;
be specific about what is being controlled with the CV’s), and
assumptions (need at least 3)
· List materials used for Control aspect of experiment and list
materials used for testing the Independent variable (ex. Acidity)
Methods
· Separate your methods section into 2 parts: Part I and Part II.
Part I will be the specific, detailed and thorough methods used
for the control experiment. Part II will be the specific, detailed
and thorough methods used for testing the independent variable.
· Detailed description of the procedure your group used for the
experiment. Enough information must be included so that
someone else could use your list of materials and procedure and
replicate the experiment exactly.
· Don’t forget to include procedure associated with analysis (ex.
Graphs and linear trendlines; include time ranges used for

trendlines)
· Must be in paragraph form, past tense, and passive voice (No
“I, we, our, my” language).
Results
You will have at least 2 data tables labeled Data Table 1:
(descriptive title), Data Table 2: (descriptive title) etc…
· Table 1: Control experiments (just alka-seltzer in water)
· Table 2: Your group data from your group’s experiment (how
the IV changed the rate of reaction)
· The data tables will start at 0 sec and continue every 10 sec
until you stopped the experiment. You will then need 4 columns
of mass (Trial 1/A-S tablet 1, Trial 2, Trial 3, and Average).
· You will need a trend paragraph for each data table
You will have 2 graphs
· Graph of original average data from the control experiment
· Graph of your experimental average data
· Graphs are labeled as Figure 1: (descriptive title) and Figure
2: (descriptive title)
· You will need a trend paragraph for each graph
· Each graph should have 3 best fit lines on it. They need to
have units included. Find the slope of the best fit lines which
will represent the rate of reaction at three sections on your
graph (beginning, middle, and end). If the best fit line is
plotted by hand, be sure to show your calculations directly on
the graph or directly after the graph. Please provide a key so
that it is easy to determine which calculation corresponds with
each line.
Discussion and Conclusion:
· Restate the hypothesis and prediction. Does the data support
or refute the hypothesis?
· Provide evidence with quantification (ex. slope values) by
discuss the rate of reaction (slope) of each condition tested.

Thoroughly, discuss the rates for each different trendline of
your graph. Next, compare the rates of just water (the very first
graph) to the rates of your experimental data. Talk about each
different rate on each graph. Why are they different? What was
happening to cause the difference? This is where you make
inferences! Remember that your goal was to determine what
makes the reaction rate faster. Make sure you refer to tables and
figures by number.
· Additional evidence must come from literature. Discuss
reaction rates and what makes chemical reactions go faster.
Also, discuss how the independent variable you chose made
your reaction rate change. If someone in the classroom did the
same type of experiment as you did (ex: acidity with HCl), you
can compare reaction rates with this group. Also, discuss the
chemical reaction that occurs and what causes the mass loss.
Use literature to help you explain why.
· Discuss possible errors. The errors must be classified as
systematic or random. Please discuss an error that actually
occurred during your experiment. What may have caused your
values for rate of reaction to be different from another groups’
even though the same conditions were evaluated? What could
have been wrong with your experiment or theirs? What caused
your rates to vary between experiments (looking at raw data
verses average data or between multiple trials)? What makes
your data different than what the literature says? What could
you have changed to make your data better?
· Assumptions should be discussed thoroughly. This means you
need to tell the reader how the assumptions affected or did not
affect the results, and why you think that.
· Shortcomings need to be discussed as improvements that could
be made to make the results better if the experiment were run
again. Give specific examples!

· Conclusion: Restate the hypothesis, whether it was supported
or refuted, then support that finding with a summary of actual
data.
(Need to use at least one reference in the Discussion section.
More are welcome.)
References:
· Must use at least 2 in the paper, one in the Introduction
section and one in the Discussion section.
· One of the references may be your book, with regards to the
chemical equation.
· You may use the ACS format, similar to the termite lab report
(the document in Pilot about the various ACS formats may be
helpful in generating the appropriate format).

QUICK GUIDE: ACS CITATION STYLE
The ACS Style Guide, 3
rd
ed., is the standard citation style for chemistry. This Quick
Guide includes the most
common formats from that publication. Examples of
publication types not included in the ACS Style Guide were
created based on the most relevant examples available. If
writing for publication you should also check the
“guide to authors” for the journal to which you are submitting
your manuscript.
BOOKS
Several factors, such as whether a book is in a series, is cited in
its entirety or only in part, has different
editions, etc. can cause variations in the citation format. These
are some common formats.

SCIFINDER SCHOLAR AND OTHER INDEXES
An author may need to cite an abstract from a source rather than
the original document. When citing indexes
like SciFinder Scholar or PubMed, the citation to the original
publication follows the format for that type of
publication (journal articles, patents, books, etc.) and is
followed by the citation to the abstract.

NOTES
Journal abbreviations
Chemists use standard abbreviations for journal titles and the
names of conference proceedings. These are
published in CASSI, the Chemical Abstracts Service Source
Index.
Personal names
Personal names often cause difficulties when preparing
bibliographies or reference lists. Many western
European names are arranged with the given name first and the
family name last, so that in a bibliography the
family name would come first, followed by a comma and then
the given name (or initial).
Not all western European names follow this pattern, and names
of authors from other parts of the world
certainly do not. The Chicago Manual of Style has an excellent
discussion of the rules for personal names
(sections 8.5-8.20) and alphabetizing (sections 18.69-18.87).

Directions for Multiple Trendlines on a Single Graph
· After you've created your graph, right click on the graph and
click on Select Data.
· Click on the + button and add a title for this data (ex.
Trendline 1). Then click on the little box to the right of the x
values and select your x data for your first trendline.
· Then click on the little box to the right of the y values and
select your y values for your first trendline.
· Then close out of the Select Data box.
· Right click on the new data points and click Add Trendline.
Make sure that it is linear and select to include the individual
equation.
· You can then click on the text box with the equation in it, and
add in the appropriate units for the slope and y-intercept.
· You will then repeat this for the second trendline, by right
clicking on the graph and click Select Data.
· Click on the + button and add a title for this data (ex.
Trendline 2). Then click on the little box to the right of the x
values and select your x data for your second trendline.
· Then click on the little box to the right of the y values and
select your y values for your second trendline.
· Repeat the instructions from above to add the trendline and
equation for the 2nd trendline.
· Repeat the above instructions for the 3rd trendline.
