A substance will be deliquescent if its vapour pressure is:

A

(a) Equal to the atmospheric pressure

B

(b) Equal to that of water vapour in the air

C

(c ) Greater than that of water vapour in the air

D

(d) Lesser than that of water vapour in the air

Text Solution

Verified by Experts

The correct Answer is:
D
Higher vapour pressure of `H_(2)O` in atmosphere will derive `H_(2)O` vapours to solute particles.
