Key Points: Raoult's Law as a Special Case of Henry's Law

For a solution of gas dissolved in liquid (A = solvent, B = gas):

  • If the gas perfectly obeys Raoult's Law: PB = P°B · XB
  • If it obeys Henry's Law: PB = KH · XB

When KH = P°B (i.e., vapour pressure of pure gas equals Henry's constant), Raoult's Law becomes a special case of Henry's Law.

Henry's Law applies when the solute is a gas; Raoult's Law applies when the solute is a volatile liquid.
