Аннотация:Activity coefficients in aqueous solutions of alkali metal nitrates at 298 K have been calculated by the generalized Debye–Huckel theory using experimental values of the static dielectric constant of solutions. It has been shown that calculation without optimization of model parameters in a number of systems reproduces the dependence of activity coefficients on cation radius and the levelling of potassium, rubidium, and cesium cations influence on activity coefficients in the presence of nitrate ions. The effect of hydration and ion association on the thermodynamic properties in the series of studied systems has been considered.
