Assertion: When a solution is separated ...

Assertion: When a solution is separated from the pure solvent by a semi-permeable membrane, the solvent molecules pass through it from pure solvent side to the solution side.
Reason: Diffusion of solvent occurs from a region of high concentration solution to a region of low concentration solution.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true, but reason is not the correct explanation of assertion.

C

If assertion is true, but reason is false.

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
C
Assertion is correct statement but reason is a wrong statement because a semipermeable membrane allows the solvent molecules to pass through a solution of lower concentration to that of higher concentration. This flow of solvent molecule from solvent side to the solution side through a selectively permeable semi-permeable membrane is called as osmosis. Thus, assertion is correct but reason is wrong.
