| Abstract: | A thermodynamic model for aqueous solutions of strong electrolytes has been developed in order to evaluate activity and osmotic coefficients of multicomponent solutions of strong electrolytes.The excess Gibbs energy is given by three contributions: the Debye-Huckel term, the Born term and the Wilson term, the latter taking into account the effect of short range intermolecular forces.The proposed model needs only binary parameters, which can be obtained by fitting experimental data of binary aqueous electrolyte solutions. This makes it valuable when experimental data of multicomponent solutions are lacking.The proposed model can be used in calculating boiling point elevation or solubility of strong electrolytes in multicomponent aqueous solutions in a wide range of temperature and concentration. |
