An ionic compound that attracts atmospheric water so strongly that a hydrate is formed is said to be :

A

Dilute

B

Hygroscopic

C

Immiscible

D

Miscible

Text Solution

Verified by Experts

The correct Answer is:
B
Certain compounds combine with the moisture os atmosphere and are converted into hydroxides or hydrates. Such substances are called hygroscopic. `e.g.`, anhydrous `CuSO_(4)`, quick lime `(CaO)`, anhydrous `Na_(2)CO_(3)` etc.
