Why detergents are better cleansing agents than soaps ? Explain.

Text Solution

Verified by Experts

Detergents and soaps both are cleansing agents but detergents can be used even in hard water whereas soaps cannot be used in hard water.
Soaps forms an insoluble precipitate with calcium and magnesium ions found in hard water .This precipitate is called as scum which sticks to the clothes and makes the cleaning even more difficult.
On the contray ,detergents have charged ends and do not form insoluble precipitates with calcium and magnesium ions. The cleansing a action of detergents is stronger than soaps .They can be used with both hard or soft water ,therefore it is convenient to use them in place of soaps.
