Pick up the wrong statement: a)Deliquescent salts are highly soluble in water. b)Vapour pressure of water in hygroscopic substances in their solution state is lower than humidity of air. c)Efflorescent crystals have higher vapour pressure of water than humidity of air. d)For isotonic solution concentrations of two solutions must be always same.

A

Deliquescent salts are highly soluble in water

B

Vapour pressure of water in hygroscopic substances in their solution state in lower than humidity of air

C

Efforescent crystal have higher vapour pressure of water than humidity of air

D

For isotonic solution concentrations of two solutions must be always same

Text Solution

Verified by Experts

The correct Answer is:
D
`c_(1)=c_(2) or c_(1) gt c_(2)` for isotonic solution depending on the nature solute.
