thanks :) The boiling point and freezing points of a solution differs from those of the pureliquid. This can be explained in terms of vapor pressure. Since the vaporpressure of the solvent above the solution is lower, a higher temperature isneeded to reach a point where the vapor pressure of the liquid meets therequired 1 atm, and the boiling point is elevated. The lower vapor pressurechanges the entire phase diagram for the solvent, and the resulting changepushes 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 thefreezing point is also lower.The change in the boiling point for a solution containing a molecular solute,AT, can be calculated using the equationATb = Kb.min 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 becalculated in a similar manner usingAT₁ = Kf.min which m is the molality of the solution and Kf is the molal freezing-point-depression constant for the solvent.
