The SOLGASWATER program was written by Gunnar Eriksson at the Department of Inorganic Chemistry of the University of Umeå, Sweden. The code is based on a constrained free energy minimisation method. It must be recalled that the free energy change of a reaction is: ΔG° = −RT lnK°, where K° is the equilibrium constant.
