Answers
Answer:
Soap is made in the laboratory by the process of Saponification. The process involves reacting a vegetable oil like palm oil or olive oil with an alkali like Sodium Hydroxide. This reaction is exothermic in nature, liberating heat during the reaction
For marking brainlaiest you get option
Soaps : Soaps are generally mixtures of sodium and potassium salts of higher fatty acids such as stearic, palmitic and oleic acids. For effective cleansing action of soap, its fatty acid unit must contain 12 to 18 carbon atoms. Soaps with less than 12 carbon fatty acids are comparatively soluble in water whereas soaps containing more than 22 carbon atoms are not useful because of their insolubility in water.
Preparation : Shaving creams, shampoos etc. are mostly potassium soaps.
Soaps are usually obtained by the hydrolysis of oils and fats with sodium or potassium hydroxide.
Transparent soaps are prepared by dissolving ordinary soaps in alcohol and then removing the insoluble part by filtration. The solid transparent mass is obtained on evaporating off alcohol.
