State

Freezing point depression is the drop in a solution's freezing point below its solvent's, proportional to solute molality through a separate constant.

Show

Salting an icy road lowers the mixture's freezing point below 0 °C, melting ice that would stay frozen.

Watch for

Freezing and boiling constants differ for one solvent — using one in place of the other swaps in the wrong number.
