Abstract

The activity coefficients of sodium bromide in the ternary system NaBr+NaClO4+H2O were determined at 25°C and constant ionic strength of 0.1, 0.5, 1, 2, and 3 mol-kg−1 from emf of the cell without, liquid junction

$$ISE - Na|NaBr(m_A ), NaClO_4 (m_B ), AgCl_{(s)} 1 Ag$$

The experimental activity coefficients were comparatively analyzed by using the Harned, Scatchard, Pitzer and Lim-HOLL treatments. All these methods are adequate for the analysis of the experimental data. The results have been compared with those of Lanier for the system: NaCl+NaClO4+H2O. The Gibbs excess energy of mixing was obtained and qualitatively interpreted in terms of ionic interactions.
