Question

Which of the following have the hygroscopic nature?

• A. $ CaS{{O}_{4}} $ and $ MgS{{O}_{4}} $
• B. $ Ca{{(OH)}_{2}} $ and $ L{{i}_{2}}C{{O}_{3}} $
• C. $ CaC{{l}_{2}},\,MgC{{l}_{2}} $ and $ LiOH $
• D. $ CaS{{O}_{4}} $ and $ CaC{{l}_{2}} $

Answer 1

Answer: (C)

The hydroxides of Cs, Rb, K, Na, Li are hygroscopic. $ CaC{{l}_{2}} $ and $ MgC{{l}_{2}} $ are also hygroscopic in nature. Hygroscopic means those compounds which absorb moisture from air.
