Abstract:

Two forms of the lever rule in the two-phase and three-phase regions of a multi-component system are discussed in this article. As for the two-component system, the cooling curves of solutions are explained with the lever rule in a three-phase line and the freezing point depression equation. A similar form of the lever rule is presented for three points on a line segment in a three-phase diagram region. This equation can be exploited to prepare the solution with desired concentrations of a multi-component system and to draw three-phase diagrams.
