Define :

(a) Soft water

(b) Hard water

Answer 1

(a) Soft water: The water present in different natural sources has different substances dissolved in it.
The water drawn from certain sources forms a lather with soap rather easily. Such water is called soft
water.
(b) Hard water: Water obtained from various sources does not easily form a lather with soap, rather it
forms a white sticky scum or a precipitate. This water is called hard water.
