Osmotic pressureMediumQuestion 750008

Question

The osmotic pressure of a solution is given by:
  1. A
    π = CRT (or MRT)
    Correct
  2. B
    π = nRT/V²
  3. C
    π = kT/C
  4. D
    π = RT × density

Correct answer

π = CRT (or MRT)

Explanation

Osmotic pressure: π = CRT = MRT, where C = M = molar concentration, R = gas constant, T = temperature in K. Analogous to the ideal gas equation.
