Key Concepts

Osmotic Pressure

Osmotic pressure is the pressure required to counteract the flow of the solvent through the semipermeable membrane. It is a measure of the tendency of a solvent to move into a solution with a higher solute concentration and plays a critical role in determining the direction and magnitude of the solvent flow during osmosis.

Concentration Gradient

A concentration gradient refers to the difference in the concentration of a substance across a region. In the context of osmosis, it is the difference in solute concentration on either side of the membrane that drives the solvent to move from an area of lower solute concentration to an area of higher solute concentration.

Osmosis

Osmosis is the movement of a solvent across a semipermeable membrane from an area of lower solute concentration (and thus higher solvent concentration) to an area of higher solute concentration (and lower solvent concentration). This process occurs to equalize the chemical potential of the solvent on both sides of the membrane.

Semipermeable Membrane

A semipermeable membrane is a barrier that allows certain molecules, such as the solvent, to pass through while blocking others, typically larger solute particles. This selective permeability is key to processes like osmosis, where only the solvent moves in response to concentration differences.
