Boiling Point Elevation
Captions available
The idea
Boiling point elevation is the rise in a solution's boiling point above its solvent's, proportional to solute molality through a solvent-specific constant.
In practice
Adding ethylene glycol to a car radiator's water raises its boiling point above 100 °C.
Where people slip
The elevation constant depends on the solvent's identity, not the solute's — different solvents give different elevations for the same solute.
