Solution

The correct option is A
True

Soaps are the sodium or potassium salts of higher fatty acids whereas Detergents are sodium or the potassium salts of aromatic sulphonic acids. Soaps are used for cleaning with soft water only since they are ineffective in hard water. Detergents are used for washing purposes in both soft water and hard water. A detergent is a better cleansing agent as compared to soap and is often called as soapless soap.
