Abstract Electromotive-force measurements are reported for mixtures of HBr and BaBr2 in water at 25°C at constant total ionic strengths. Activity coefficients for HBr were analyzed using Pitzer's equations and Scatchard's neutral-electrolyte treatment. Both methods gave comparable results if the effects of higher-order electrostatic terms on the H+−Ba+2 interactions were included in Pitzer's treatment. Furthermore, the value of the H+−Ba+2 interaction parameter, θ(s), which should be independent of the anion, is indeed close to that for binary mixtures of these ions having chloride as common ion.
