**Abstract Scope** |
Phase diagram sections of aqueous systems are calculated thermodynamically employing data from large evaluated databases. Axes and constants can be temperature, mass or molar ratios, and/or chemical potentials for systems of any number of components and with non-ideal solutions. Iso-Eh and iso-pH lines are calculated and plotted. The equilibrium amounts and compositions of all phases can be readily displayed at any point on a diagram. |
