Prediction of the Water Activity in Multicomponent Solutions by a Simple and Accurate Equation and Derivation of Zdanovskii’s Rule

Autor: Abel C. Chialvo, Maria Rosa Gennero

Publikováno v: Journal of Solution Chemistry. 48:395-411

A simple equation is derived for the prediction of the water activity as a function of the molal concentrations of a multicomponent mixture, a1(m2 , m3 ,.., mn+1). It consists basically of a series expansion whose coefficients are determined from the

Alternative formalism for the evaluation of the activity coefficients on ternary electrolyte solutions from osmotic coefficient data

Autor: María R. Gennero de Chialvo, Francisco Javier Passamonti, Abel C. Chialvo

Publikováno v: Fluid Phase Equilibria. 547:113169

An alternative method is presented, which is independent of any physicochemical model of the electrolyte solution, for the evaluation of the mean ionic activity coefficient in molal scale, γ ± i (i: 2,3), of the solutes of a ternary solution (1–2
