Boiling equation
WebAug 23, 2024 · A mathematical equation is used to calculate the boiling point elevation or the freezing point depression. The boiling point elevation is the amount that the boiling … WebFeb 3, 2024 · We can define the boiling point elevation ( ΔTb) as the difference between the boiling points of the solution and the pure solvent: ΔTb = Tb − T0 b where Tb is the boiling point of the solution and T0 b is the boiling point of the pure solvent. We can express the relationship between ΔTb and concentration as follows ΔTb = mKb
