WebBoiling-point elevation. Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. WebApr 9, 2024 · Δ T b α m. Δ T b = K b × m. Where, ΔTb = T0b − Tb is the elevation in Boiling Point, ‘m’ is the molality, ‘Kb’ is the molal elevation, Boiling Point or ebullioscopic constant whose value depends only on …
