Lecture on the condensed-phase equilibrium of two- and three-component systems. For 2-component systems, the example system discussed is a binary system in which the components are completely miscible in the liquid phase. The application of the lever rule is also discussed. For 3-component systems, the Stokes-Rozeboom diagram is introduced with application to liquid-liquid-liquid systems and solid-solid-liquid systems.
