About Osmotic Pressure

Osmotic pressure is the pressure required to prevent the flow of solvent through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.

Formula:

π = iMRT

Where π is osmotic pressure, i is van't Hoff factor, M is molarity, R is gas constant, and T is temperature in Kelvin.

Applications:

  • Biological systems (cell membranes)
  • Water purification (reverse osmosis)
  • Food preservation
  • Medical applications (dialysis)
