Kashish Sharma thanks their teacher and principal for allowing them to do a project comparing the foaming capacities of different soaps. The student tests 5 soap brands - Santoor, Dove, Cinthol, Tetmosol, and Lux. They find that Santoor has the highest foaming capacity and cleansing action, taking the longest for foam to disappear, while Lux has the lowest foaming capacity. The experiment shows Santoor is the most effective soap for cleaning.

soap is a salt of a fatty acid,.
Consumers mainly use soaps as surfactants for washing, bathing, and cleaning, but they are also used in textile spinning and are important components of lubricants.
Soaps for cleansing are obtained by treating vegetable or animal oils and fats with a strongly alkaline solution

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
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.

6. • Soaps and detergents remove dirt and grease from skin and
clothes. But all soaps are not equally effective in their
cleaning action. Soaps are the Na and K salts of higher fatty
acids such as Palmitic acid, Stearic acid and Oleic acid. The
cleansing action of soaps depends on the solubility of the
long alkyl chain in grease and that of the -COONa or the -
COOK part in water. Whenever soap is applied on a dirty wet
cloth, the non polar alkyl group dissolves in grease while the
polar -COONa part dissolves in water. In this manner, an
emulsion is formed between grease and water which appears
as foam. The washing ability of soap depends on foaming
capacity, as well as the water used in cleaning. The salts of
Ca and Mg disrupt the formation of micelle formation. The
presence of such salts makes the water hard and the water is
called hard water. These salts thus make the soap inefficient
in its cleaning action. Sodium Carbonate when added to hard
water reacts with Ca and Mg and precipitates them out.
Therefore sodium carbonate is used in the treatment of hard
water. This project aims at finding the foaming capacity of
various soaps and the action of Ca and Mg salts on their
foaming capacity.
•
7. • Soap is an anionic surfactant used in conjunction
with water for washing and cleaning, which
historically comes either in solid bars or in the
form of a viscous liquid. Soap consists of sodium
or potassium salts of fatty acids and is obtained
by reacting common oils or fats with a strong
alkaline in a process known as saponification.
The fats are hydrolyzed by the base, yielding
alkali salts of fatty acids (crude soap) and
glycerol.
• The general formula of soap:
• Fatty end water soluble end
• CH3-(CH2)n - COONa
• Soaps are useful for cleaning because soap
molecules have both a hydrophilic end, which
dissolves in water, as well as a hydrophobic end,
which is able to dissolve non polar grease
molecules. Applied to a soiled surface, soapy
water effectively holds particles in colloidal
suspension so it can be rinsed off with clean
water. The hydrophobic portion (made up of a
long hydrocarbon chain) dissolves dirt and oils,
while the ionic end dissolves in water. The
resultant forms a round structure called micelle.
Therefore, it allows water to remove normally-
insoluble matter by emulsification.
8. • The most popular soap making process
today is the cold process method, where
fats such as olive oil react with strong
alkaline solution, while some soapers use
the historical hot process.
• Handmade soap differs from industrial
soap in that, usually, an excess of fat is
sometimes used to consume the alkali
(super fatting), and in that the glycerin is
not removed, leaving a naturally
moisturizing soap and not pure detergent.
Often, emollients such as jojoba oil or
Shea butter are added 'at trace' (the point
at which the saponification process is
sufficiently advanced that the soap has
begun to thicken), after most of the oils
have saponified, so that they remain
unreacted in the finished soap.
9. • Soap is derived from either vegetable or
animal fats. Sodium Tallowate, a
common ingredient in much soap, is
derived from rendered beef fat. Soap can
also be made of vegetable oils, such as
palm oil, and the product is typically
softer.
• An array of saponifiable oils and fats are
used in the process such as olive,
coconut, palm, cocoa butter to provide
different qualities. For example, olive oil
provides mildness in soap; coconut oil
provides lots of lather; while coconut and
palm oils provide hardness. Sometimes
castor oil can also be used as an
ebullient.
• Smaller amounts of unsaponifable oils
and fats that do not yield soap are
sometimes added for further benefits.
10. • In cold-process and hot-process soap
making, heat may be required for
saponification.
• Cold-process soap making takes place at a
sufficient temperature to ensure the
liquification of the fat being used.
• Unlike cold-processed soap, hot-processed
soap can be used right away because the
alkali and fat saponify more quickly at the
higher temperatures used in hot-process
soap making. Hot-process soap making was
used when the purity of alkali was
unreliable.
• Cold-process soap making requires exact
measurements of alkali and fat amounts and
computing their ratio, using saponification
charts to ensure that the finished product is
mild and skin-friendly.
11. • Soap samples of various brands are
taken and their foaming capacity is
noticed.
• Various soap samples are taken
separately and their foaming capacity
is observed. The soap with the
maximum foaming capacity is thus,
said to be having the best cleaning
capacity.
• The test requires to be done with
distilled water as well as with tap
water. The test of soap on distilled
water gives the actual strength of the
soaps cleaning capacity. The second
test with tap water tests the effect of
Ca2+ and Mg2+ salts on their foaming
capacities.
12. • In the hot-process
method, alkali and
fat are boiled
together at 80–100
°C until
saponification
occurs, which the
soap maker can
determine by taste
or by eye.
• After saponification
has occurred, the
soap is sometimes
precipitated from the
solution by adding
salt, and the excess
liquid drained off.
The hot, soft soap is
then spooned into a
mold.
• A cold-process soap
maker first looks
up the
saponification value
of the fats being
used on a
saponification
chart, which is then
used to calculate
the appropriate
amount of alkali.
Excess unreacted
alkali in the soap
will result in a very
high pH and can
burn or irritate
skin. Not enough
alkali and the soap
are greasy
13. OBJECTIVE:
TO COMPARE THE FOAMING
CAPACITY OF SOAPS
• Theory : The foaming capacity of soap depends
upon the nature of the soap and its
concentration. This may be compared by shaking
equal volumes of solutions of different samples
having the same concentration with same force
for the same amount of time. The solutions are
then allowed to stand when the foam produced
during shaking disappears gradually. The time
taken for the foam to disappear in each sample is
determined. The longer the time taken for the
disappearance of the foam for the given sample of
soap, greater is its foaming capacity or cleansing
action.
Requirements: Five 100ml conical flasks, five test
tubes, 100ml measuring cylinder, test tube stand,
weighing machine, stop watch.
• Chemical Requirements: Five different soap samples,
distilled water, tap water.
14. • Procedure:
• 1. Take five 100ml conical flasks and
number them 1,2,3,4,5. Put 16ml of water in
each flask and add 8 Gm of soap.
• 2. Warm the contents to get a solution.
• 3. Take five test tubes; add 1ml of soap
solution to 3ml of water. Repeat the process
for each soap solution in different test tubes.
• 4. Close the mouth of the test tube and
shake vigorously for a minute. Do the same
for all test tubes and with equal force.
• 5. Start the timer immediately and notice the
rate of disappearance of 2mm of froth.
• Observations:
• The following outcomes were noticed at the
end of the experiment:
15. • Result:
• The cleansing capacity of the soaps taken is in the
order:
• Santoor > Dove > Cinthol > Tetmosol > Lux
• From this experiment, we can infer that Santoor has
the highest foaming capacity, in other words, highest
cleaning capacity.
• Lux, on the other hand is found to have taken the least
amount of time for the disappearance of foam produced
and thus is said to be having the least foaming capacity
and cleansing capacity.
• Test for hardness in water
• Test for Ca2+ and Mg2+ salts in the water supplied
• Test for Ca2+ in water
• H20+NH4Cl + NH4OH+ (NH4)2CO3
• No precipitate
• Test for Mg2+ in water
• H2O +NH4Cl+ NH4OH + (NH4)3PO4
• No precipitate
• The tests show negative results for the presence of the
salts causing hardness in water. The water used does
not contain salts of Ca2+ and Mg2+. The tap water
provided is soft and thus, the experimental results and
values hold good for distilled water and tap water.
