Chemistry Question on Solutions
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
is greater than that of water vapour in air
Answer
is less than that of water vapour in air
Explanation
Solution
Deliquescence is a phenomenon by virtue of which substance absorbs moisture from air and gets dissolved in it. For this to happen the vapour pressure of water vapours in air should be greater than that of the solution of substance.
