Interpreting Freezing Point Depression from the Viewpoint of Entropy

Faculty of Chemistry, Northeast Normal University, Changchun 130024, P. R. China

The equation for depression of the freezing point for dilute solution is derived on the basis of △G=△H-T△S. The change of entropy in the solution before and after phase transition reveals that the depression of the freezing point is originated from the larger entropy change in the process of dissolution than that in fusion. The further application of this equation is discussed in a more general manner.
- Freezing point depression,
- Colligative properties of dilute solution,
- Phase transition entropy
