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

A

An increase in the boiling point of the solution

B

A decrease in the boiling point of solvent

C

The solution having a higher freezing point than the solvent

D

The solution having a lower osmotic pressure than the solvent

Text Solution

Verified by Experts

The correct Answer is:
A

When vapour pressure of solvent decreases, then the boiling point of solvent increases.
Vapour pressure of solvent `prop(1)/("Boiling point of solvent")`.
