प्रश्न
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 solvent occurs from a region of high concentration solution to a region of low concentration solution.

उत्तर
Assertion and reason both are correct statements but reason is not correct explanation for assertion.
Explanation:
The Assertion is correct because it describes osmosis - solvent moves from pure solvent (high solvent concentration) to solution (low solvent concentration) through a semipermeable membrane.
The Reason is wrong because solvent does not move from high concentration solution to low concentration solution; it moves from high solvent concentration to low solvent concentration.
