This paper reports the thermodynamic properties of CsF in (Urea + H2O) or (N-methylformamide + H2O) mixed solvents by potentiometric method at 298.2 K. The experimental data are fitted using the Pitzer, modified Pitzer and extended Debye-Htickel equation. The mean activity coefficients, osmotic coefficient and excess Gibbs free energies are obtained and the corresponding derived parameters are reported at the same time. The standard free energy of transference and the primary hydration number are also obtained.
