Notes:
Isoactive-solvent (ISAC) theory is a thermodynamic framework for the case where the components of a solution exist in different pure states: liquid solvent and gaseous solutes (absorption of gases); solid solvent and liquid solutes (sorption of liquids); and liquid solvent and solid solutes (solubility of mixed electrolytes). Properties of mixed solutes are predicted from known activities of single solutes by assuming that solute-solute (but not solute-solvent) molecular interactions are ideal. Equations for an ISAC ideal solution are exact in the limiting case of a solution of identical solutes. The thermodynamic potential is a Legendre transformation of the Gibbs free energy: Ψ = G - μ1n1, where the solvent is component number 1. The ISAC standard state is the real single-solute mixture.
