Question
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.
Options
Assertion and reason both are correct statements and reason is correct explanation for assertion.
Assertion and reason both are correct statements but reason is not correct explanation for assertion.
Assertion is correct statement but reason is wrong statement.
Assertion and reason both are incorrect statements.
Assertion is wrong statement but reason is correct statement.
Solution
Assertion and reason both are correct statements but reason is not correct explanation for assertion.
Explanation:
Asseration is correct statement but reason is a wrong statement because a semipermeable membrance 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 membrance is called osmosis.
