Assertion : When a solution is separated...

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

A

Assertion and reason both are correct statements and reason is correct explanation for assertion.

B

Assertion and reason both are correct statements but reason is not correct explanation for assertion.

C

Assertion is correct statement but reason is wrong statement.

D

Assertion and reason both are incorrect statements.

Text Solution

Verified by Experts

The correct Answer is:
B
Explantion : Assertion is correct statement but reason is a wrong statement because a semipermeable membrane permits solvent molecules to pass through a solution of lower concentration to that of higher concentration Flow of solvent molecule from solvent side to solution side through semipermeable membrane is called osmosis.
