Question

Would you be able to check if water is hard by using a detergent?

Answer 1

Answer:

It is not possible to check if water is hard by using a detergent because detergents are salts of ammonium or sulphonates of long chain carboxylic acids. Unlike soaps they do not react with calcium and magnesium to distinguish nature of water.

Answer 2

Answer:

Detergent forms lather with hard and soft water both, while a soap forms lather with soft water only. Thus, it is not possible to check if the water is hard or not by using a detergent.
