A substance will be deliquescent if its vapour pressure :

A

is equal to the atmospheric pressure

B

is equal to that of water-vapour in air

C

is less than that of water-vapour in air

D

D is greater than that of water-vapour in air

Text Solution

Verified by Experts

The correct Answer is:
C
Deliquescent substances absorb moisture form air and get dissolved in it. For this to happen, the vapourpressure of water vapours in air should be greater than that of solution or substance.
