Answer 1

Answer:

Sodium Chloride

Explanation:Since it contains calcium chloride and magnesium chloride as impurities which are deliquescent.

Answer 2

Iron III chloride salt is deliquescent.

Salts can be categorised on the basis of absorption of water. Deliquescent salts or hygroscopic salts are the ones that can absorb water or moisture from surroundings thus getting wet.

Iron III chloride salt is deliquescent. Sodium chloride or table salt is deliquescent at higher temperature and humidity.

Opposite for deliquescence is efflorescence, which releases moisture. The salts become powdered after loosing moisture. Glauber's salt and washing soda are the examples.
