Imbibition/diffusion is the movement of substances from the region of their higher concentration to the region of lower concentration.

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.
