Question

what is the difference between freezing point and freezing point depression

Answer 1

The solute lowers the vapor pressure of the solvent resulting in a lowering of the freezing point of the solution compared to the solvent. The freezing point depression is the difference in temperature between the freezing point of the pure solvent and that of the solution. On the graph, the freezing point depression is represented by 

Answer 2

Answer:

A solution will have a lower freezing point than a pure solvent. The freezing point is the temperature at which the liquid changes to a solid. The freezing point depression is the difference in the freezing points of the solution from the pure solvent.
