soaps and detergents
is a water pollutnntiand why

Answer 1

Detergents are the better cleansing agents than soapsbecause detergents work ascleansing agent both in hard and soft water. Soaps are not suitable for use with hard water .The charged ends of detergents do not form insoluble precipitates with calcium and magnesium ions in hard water.

I hope this helps you.

Answer 2

Reaction of calcium and manganese salts cause hardness of water. This problem is overcome by using detergents. They are generally ammonium or sulphonate salts of long chain carboxylic acids . The charged ends of these compounds do not form insoluble precipitates with the Ca and Mg ions in hard water. Thus they remain effective in hard water.
