A review of approaches for solving of basic chemical and ionic equilibrium is carried out. An extension for simultaneous reactions is then explained. Non-stoichiometric forms of equilibrium conditions and method of solving chemical equilibrium in systems with high number of reactions is discussed. Thermodynamic properties of the system containing solid solutions and alloys are demonstrated as well.
