Osmotic Pressure
What is Osmotic Pressure?
Osmotic pressure (π) is the minimum pressure that must be applied to a solution to prevent the inward flow of solvent molecules through a semipermeable membrane from pure solvent. It is given by the van't Hoff equation: π = iMRT, where i is the van't Hoff factor, M is molarity, R is the gas constant, and T is temperature. Osmotic pressure is a colligative property and is important in intravenous drug delivery and desalination.
