摘要: The stepwise solvation-equilibrium model of Stokes and Robinson is used for a description departures from ideality in ionic solutions. It shown how to construct thermodynamically consistent including solvation effects. Simple expressions are derived the mean ion number. applied strong electrolyte solutions (pure water+salt mixed aqueous solvent+salt) by taking spherical approximation (MSA) long-range contribution Gibbs energy local composition model, nonrandom two-liquid (NRTL) short-range contribution.
