The boiling point and freezing points of a solution differs from those of the pure liquid. This can be explained in terms of vapor pressure. Since the vapor pressure of the solvent above the solution is lower, a higher temperature is needed to reach a point where the vapor pressure of the liquid meets the required 1 atm, and the boiling point is elevated. The lower vapor pressure changes the entire phase diagram for the solvent, and the resulting change pushes the triple point of the solution to a lower temperature value. The solid- liquid phase equilibria curve is related to the location of the triple point, and the freezing point is also lower. The change in the boiling point for a solution containing a molecular solute, AT, can be calculated using the equation ATb = Kb.m in which m is the molality of the solution and K₁ is the molal boiling-point- elevation constant for the solvent. The freezing-point depression, ATF, can be calculated in a similar manner using AT₁ = Kf.m in which m is the molality of the solution and Kf is the molal freezing-point- depression constant for the solvent.
