Abstract

A mole-fraction-based thermodynamic model is used to represent available activity data, salt solubilities, and electrodynamic balance measurements for aqueous NaCl, Na₂SO₄, NaNO₃ and their mixtures at 298.15 K. The results are presented as fitted ion-interaction parameters and equilibrium constants. These enable ion and solvent activities, and saturation with respect to five possible solid phases (NaCl, NaNO₃, Na₂SO₄ · 10H₂O, Na₂SO₄, and NaNO₃ · Na₂SO₄ · H₂O) to be calculated for all mixture compositions to relative humidities of ≤ 60%, and to high degrees of supersaturation with respect to the dissolved salts. Extension of the model to other systems is discussed.
