ABSTRACT
In this paper, CsF + CsBr + H2O and CsF + CsNO3 + H2O mixed electrolyte systems were investigated by potentiometric method. The experimental data were modeled by connecting Nernst equation with Pitzer or Harned model. The mean ionic activity coefficients of CsF, A, and CsBr or CsNO3, B, were calculated. Moreover, other properties, such as mean ionic activity coefficients in pure and trace quantities (0 and tr), osmotic coefficients, , excess Gibbs energies, GE, the change in excess Gibbs energy of the mixture, Gmex , were obtained and discussed.
