Abstract Activity coefficients for NaBr in the system NaBr+NaFormate+H2O at 25°C were determined from emf measurements at different total ionic strengths. At each total ionic strength, the measurements were carried out at different Na-Formate/NaBr ionic strength ratios. The experimental activity coefficients were comparatively analyzed using Scatchard's, Pitzer's and Lim's methods. Although all these models can be successfully applied to the analysis of this mixed system, the All Mixing Coefficients (LA) and Consistency Test (LT) models lead to better fittings than the others.
