Abstract

The stepwise solvation-equilibrium model of Stokes and Robinson is used for a description of departures from ideality in ionic solutions. It is shown how to construct a thermodynamically consistent model including solvation effects. Simple expressions are derived for the mean ion solvation number. The model is applied to strong electrolyte solutions (pure water + salt and mixed aqueous solvent + ...
