Question
What are soaps? How soaps are prepared?
✓
Answer
i. Soaps are sodium or potassium salts of long chain fatty acids.
ii. They are obtained by alkaline hydrolysis of natural oils and fats with NaOH or KOH. This is called saponification reaction.
iii. Chemically, oils are triesters of long chain fatty acids and propane-1,2,3-triol (commonly known as glycerol or glycerin).
iv. Saponification of oil produces soap and glycerol as shown in the reaction below:
