Question

Name any one salt present in hard water.

Answer 1

Understanding the concept:

Water that contains magnesium & calcium salts in the form of bicarbonates, chlorides, and sulfates is called hard water.

Explanation of hard water with examples :

• Because the water contains various minerals and salts, soaps and detergents produce a thick scum rather than a lather.
• As a result, dirt cleaning becomes much more difficult.
• Calcium and Magnesium salts are mostly found in hard water.
