Study Notes
Osmotic Pressure
- Osmotic pressure measures the pressure required to prevent the flow of water into a solution through a semipermeable membrane.
- As solute concentration increases, osmotic pressure also increases.
- The unit of measurement for osmotic pressure is atmospheres (atm) or pascals (Pa).
Calculating Osmotic Pressure
- The formula to calculate osmotic pressure is: π = iMRT, where π is the osmotic pressure, i is the Van't Hoff factor, M is the molarity of the solution, R is the gas constant, and T is the temperature in Kelvin.
Temperature and Van't Hoff Factor
- Osmotic pressure increases with an increase in temperature.
- For a non-electrolyte solute, the Van't Hoff factor (i) is 1, indicating that the solute does not dissociate in solution.
