Answer 2

Soaps are the sodium or potassium salts of long chain of carboxylic acids.

Soaps are basic in nature .
There are two ends of soap.
One is ionic end that dissolves in water and another is carbon end that dissolves in oil.
The soap forms micelles that is one end faces the oil drop and another faces outside to water

When soap reacts with calcium and magnesium salts it forms insoluble precipitate in water leading to hardness of water.Therefore it isn't effective in cleaning clothes.
