Freezing Point Depression
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
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.
