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.

पर्याय

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.
