Osmosis and Osmotic Pressure

Osmosis and Osmotic Pressure. Osmosis: The selective passage of solvent molecules through a porous membrane from a dilute solution to a more concentrated one. Osmotic pressure (? or ?): The pressure required to stop osmosis. ? = i ? M RT (Approximate Form) R = 0.08206 (L ? atm)/(mol ? K).
