ABSTRACT

This article investigated the thermodynamic properties in a ternary system (CsF/RbF + DMF/DMA + H2O) at T = 298.15 K using potentiometric methods. The experimental data were correlated using the Pitzer and extended Debye Huckel equations. The mean activity coefficients, excess Gibbs free energy and the standard Gibbs free energy of transfer, together with the parameters of above thermodynamic models, were determined.
