when does osmosis occur
Osmosis-Osmosis is defined as a spontaneous net flow of solvent into a solution through a semi-permeable membrane. semi-permeable membrane-It is the membrane that allows only solvent molecules to pass through it but not solute molecules. How does osmosis occurs-Osmosis occurs on its own. It doesn't needs any external pressure or energy.When two solutions having different concentrations are seperated by a semi-permeable membrane. particles from dilute solution flow to the concentrated solution through it or solute particles flow to solvent.
