Diffusion-driven transfer of solvent molecules through a semipermeable membrane is:

1. Membranes let some particles through and not others. 2. Certain materials are generally referred to as semipermeable membranes. 3. Diffusion-driven transfer of solvent molecules through such a membrane is osmosis. 4. Transfer continues until osmotic pressure yields equal rates in both directions. _Source: OpenStax Chemistry 2e (CC BY 4.0), Ch 11 'Solutions and Colloids', sections 11.1-11.5_
