Osmotic pressure is the minimum pressure required to prevent the movement of solvent molecules into a solution through a semipermeable membrane. It is a fundamental concept in Chemistry, Biology, and medicine, important for understanding cell function and solution properties. Osmotic pressure plays a critical role in all biological processes that involve diffusion of solutes or transfer of fluids through membranes. Osmosis occurs when solvent but not solute molecules cross a semipermeable membrane from regions of lower to higher concentrations to produce equilibrium. The knowledge of osmotic pressures is important for practitioners in determining whether a parenteral solution is hypo- osmotic , iso- osmotic , or hyperosmotic. A quantitative measure of osmotic ... 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. [1] Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it was not separated from its pure solvent by a semipermeable membrane.
