State what would you observe when:

(i) Washing Soda Crystals are exposed to the atmosphere.

(ii) The salt ferric chloride is exposed to the atmosphere.

Show SolutionHide Solution↓

(i) When crystals of washing soda are exposed to air, it loses its water of crystallisation due to efflorescence.

(ii) When ferric chloride is exposed to the atmosphere, it absorbs moisture from the atmospheric air to become moist and ultimately dissolves in the absorbed water, forming a saturated solution.
