Osmosis is the diffusion of a water through a semi-permeable membrane, from a solution of low solute concentration to a solution with high solute concentration.
It is a physical process in which a solvent moves, without input of energy, across a semi-permeable membrane separating two solutions of different concentrations.
Important Points:
- It is the diffusion of water (normally) through a semi-permeable membrane.
- It is from a dilute solution to a more concentrated solution.
