Explain the Solid-Liquid Equilibria?
A freezing-point curve (freezing point as a function of liquid composition) and a solubility curve (composition of a solution in equilibrium with a pure solid as a function of tempera- ture) are different ways of describing the same physical situation. Thus, strange as it may sound, the composition xA of an aqueous solution at the freezing point is the mole fraction solubility of ice in the solution.
