Simple Boiling-Point Elevation Equation

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 formula assumes dilute ideal nonvolatile solutions.

Boiling-point elevation equals the solution molality times the ebullioscopic constant.
