Ionic solutions in the binding mean spherical approximation: thermodynamic properties of mixtures of associating electrolytes
Article Abstract:
The thermodynamic excess functions of solutions of strong electrolytes and their structure are described by an extension of the mean spherical approximation (MSA). Ionic association is also taken into account by means of Wertheim's formalism(super 18,19) in the MSA(super 20-24). Hydration effects are included using a concentration-dependent cation size and permittivity. The results show a very good representation for a number of mixed salts with a common cation. Cross parameters are introduced for salts without a common cation.

Osmotic and activity coefficients for associating electrolytes in the primitive model
Article Abstract:
The mean spherical approximation (MSA) model was used to study the osmotic and activity coefficients for aqueous solutions of pure associating electrolytes. The binding MSA was used to examine the association of ions of opposite charges for a variety of solutions of pure salts. Results showed that good fits can be obtained in some solutions of very high concentrations. A description for sulphuric acid was also obtained at low concentration.

Ionic solutions in the binding mean spherical approximation: thermodynamics of association electrolytes up to very high concentrations
Article Abstract:
A short summary of, the original binding mean spherical approximation (BIMSA) theory and derive analytical equations for the new model of species is presented. These equations are applied to fit the data for a variety of aqueous solutions of acids at 25 degree Celsius.
