Osmotic Pressure

Van't Hoff osmosis — solute particles, semipermeable membrane, water flow

Solute concentration: 30

Temperature (T): 300 K

Osmotic pressure: – | Water flow: –

Left chamber: pure water. Right chamber: solute (colored) + water. Semipermeable membrane in center allows water (blue) but blocks solute (orange). Van't Hoff: π = iMRT.
