The reasoning is this (Bodlander): Let X\ (fig. 15) be the vapor-tension curve of component A in the liquid state, y\ the solidifying point (t{) of A, and z\ the vapor-tension curve of solid A.

Now, if a small quan- tity of B is added and the solid phase which crystallizes out contains the same proportions of A and B as the liquid mixture in which it formed, the vapor tensions of the liquid and solid phases must have been lowered equally and the solidifying point will fall at y2 with the same temperature as the pure solvent. (Equality of vapor tension.
