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 (π or ∏): The pressure required to stop osmosis. π = i  M RT (Approximate Form) R = 0.08206 (L  atm)/(mol  K).

Presentation Transcript

  1. 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 (π or ∏): The pressure required to stop osmosis. π = iMRT(Approximate Form) R = 0.08206 (Latm)/(molK)

  4. Osmosis and Osmotic Pressure • Isotonic: Solutions have equal concentration of solute, and so equal osmotic pressure. • Hypertonic: Solution with higher concentration of solute. • Hypotonic: Solution with lower concentration of solute.

  5. Uses of Colligative Properties • Desalination:
