Freezing-point depression describes the phenomenon in which the freezing point of a liquid (a solvent) is depressed when another compound is added, meaning that a solution has a lower freezing point than a pure solvent. This happens whenever a solute is added to a pure solvent, such as water.

The phenomenon may be observed in sea water, which due to its salt content remains liquid at temperatures below 0 °C, the freezing point of pure water.
