CHEMISTRY PROJECT ON FOAMING CAPACITY OF SOAPS PDF

Soaps and detergents are cleaning ingredients that are able to remove oil particles from surfaces because of their unique chemical properties. Soaps are created by the chemical reaction of a jetty acid with on alkali metal hydroxide. In a chemical sense soap is a salt made up of a corboxylix acid and an alkali like sodium of potassium. The cleaning action of soap and detergents is a result of thrill, ability to surround oil particles on a surface and disperse it in water.

Soaps and detergents are cleaning ingredients that are able to remove oil particles from surfaces because of their unique chemical properties. Soaps are created by the chemical reaction of a jetty acid with on alkali metal hydroxide. In a chemical sense soap is a salt made up of a corboxylix acid and an alkali like sodium of potassium.

The cleaning action of soap and detergents is a result of thrill, ability to surround oil particles on a surface and disperse it in water. Bar soap has been used for centuries and continues to be an important product for batching and cleaning. It is also a mild antiseptic and ingestible antidote for certain poisons.

SOAP Soap is a common term for a number of related compounds used as of washing clothes or bathing. Soap is produced by a saponification or basic hydrolysis reaction of a fat or oil. Currently sodium carbonate or sodium hydroxide is used to neutralize the fatty acid and convert it to the salt.. General Overall Hydrolysis Reaction Although the reaction is shown as one step reaction, it is in fact two steps.

The net effect as that the ester bonds all broken. The glycerol turns back into an alcohol. The fatty acid is turned into a salt due to the presence of abasic solution of NaoH. In the carboxyl group, one oxygen now has a negative charge that attacts the positive sodium ion.

A molecule of soap consists of two parts. Tallow or animal fats give plimarily sodium stearate 18 carbons a very hard, insoluble soap. Fatty acids with longer chains are even more insoluble. As a matter of fact, 3inc stearate is used in talcum powders because it is water repellent.

Coconut oil is a source of lauric acid 12 carbons which can be made into sodium lourate. This soap is very soluble and will lather easily even in sea water. Fatty acids with only 10 or fewer carbons are not used in soaps because they irritate the skin and have objectionable odors Materials Required: a Apparatus One ml conical flask, 20ml test tubes, ml measuring cylinder, test tube stand, weight box, stop watch and burner.

Theory Calcium and magnesium ions present in the tap water interfere in the foaming capacity of soap. These ions combine with soap and form insoluble calcium and magnesium salts which get precipitated Therefore, the presence of these ions effect the foaming capacity of soap and hence their cleaning capacity.

When Na2CO3 is added to the tap water, calcium and magnesium ions gets precipitated as their carbonates in the presence of Na2CO3 Foaming capacity of the water increases.

Weigh accurately 0. Add 50ml of distilled water and wolm to dissolve till clear solution is obtained. Take three 20ml test tubes and label them as 1,2 and A,B and C. Add 1ml of soap solution to each tube. Cork test tube A tightly and shake vigorously for 1minute.

Place the test tube on the test tube stand and start the stop watch immediately. Note the taken for the disappearance of foam.

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. 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.
