Boiling Point Elevation

Recall that the boiling point of a liquid is the temperature at which its vapour pressure equals the applied pressure. For liquids in open containers, the applied pressure is atmospheric pressure.

It has been found that the boiling point of a solvent is elevated by dissolving a nonvolatile solute into it. Thus, solutions containing nonvolatile solutes boil at temperatures higher than the boiling point of the pure solvent. …
