Describe how soaps is prepared |
| Answer» Animal fat or vegetable oil act as glyceride or glyceryl ester. And sodium hydroxide and potassium hydroxide act as bases.Take about 30 ml of vegetable oil in a beaker. Then add 60 ml of 20% sodium hydroxide solution to it.This mixture is heated slowly till it boils. After the mixture has boiled for five to ten minutes add 5grams of sodium chloride in order to separate soap from the solution. Allow the solution to cool. The creamy layer floating on top of the solution is the soap.\xa0Thus soap is prepared by hydrolysing fat or oil with bases such as sodium hydroxide or potassium hydroxide This process of soap preparation is known as saponification.Generally soaps are prepared by heating animal fat or oil with alkalies like sodium hydroxide or potassium hydroxide. This is saponification reaction.Fat or Oil + Alkali → Soap + Glycerol\xa0 | |
