Correct Answer: Calcium and Magnesium


Solution : The correct answer is Calcium and Magnesium .

Calcium and magnesium are present in higher amounts in the hard water. Soaps do not act in hard water due to the presence of these salts, but detergents can give results in hard water. The temporary hardness of water is caused by the carbonates of calcium and magnesium. Calcium is a mineral our body needs to build and maintain strong bones.
