Question

state the disadvantage of hardness in water​

Answer 1

Answer:

(i) Bathing: Hard water does not lather freely with soap solution, but produces sticky scum on the bath-tub and body. Thus, the cleansing quality of soap is depressed and a lot of it is wasted.

(ii) Cooking: Due to the presence of dissolved hardness-producing salts, the boiling point of water is elevated.
