The solubility of common salt is 36.0 g ...

The solubility of common salt is 36.0 g in 100 g of water at `20 ^@C`. If systems, I, II and III contain 40.0, 36,0 and 20.0 g of the salt added to 100.0 g of water in each case, the vapour pressures would be in the order

A

IltII ltIII

B

IgtII gt III

C

I = II gt III

D

I = II lt III

Text Solution

Verified by Experts

The correct Answer is:
D
I is super saturated, II is saturated and III is unsaturated solution. In solution I and II, amount of dissolved substance is same.
