When a substance is dissolved in a solvent the vapour pressure of solvent decreases. This brings:

A

A decrease in boiling point of solution

B

An increase in boiling point of the solution

C

A decrease in freezing point of the solution

D

An increase in freezing point of the solution

Text Solution

Verified by Experts

The correct Answer is:
B
As we know that
Boiling point `prop (1)/("vapour pressure of liquid")`
Hence, on decreasing vapour pressure, boiling point will increase.
