Osmotic pressure

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. Potential osmotic pressure is the maxim

…solution to the solution with higher solute concentration. The transfer of solvent molecules continues until osmotic equilibrium is attained. Jacobus van 't Hoff derived thermodynamically a quantitative relationship between osmotic pressure and solute concentration, expressed in the following equation, where x…
