WebThe equation that describes the magnitude of the boiling point elevation that occurs when a solute is added to a solvent is therefore often written as follows. TBP = kbm WebThe result is that in dilute ideal solutions, the extent of boiling-point elevation is directly proportional to the molal concentration (amount of substance per mass) of the solution according to the equation: [1] ΔTb = Kb · bc where the boiling point elevation, is defined as Tb (solution) − Tb (pure solvent) .

WebBoiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, as the boiling point of a solvent increases, its freezing point decreases.
