Abstract

The present paper deals with the theoretical calculations of association constant for sonie 1-1 electrolytes, AgNO₃, LiNO₃ and KNO₃ in water-ethanol and AgNO₃, KNO₃, NaCl, KCl, RbCl and LiCl in water-dioxane mixtures by using Bjerrum, Fuoss and Denison-Ramsay theories of ionic association. The internai consistency of the calculated k_A values has been tested by plotting log k_A vs 1/D. These values are further compared with Fuoss conductances values.

Résumé

Application de diverses théories de l’association ionique au calcul des constantes d’association de divers électrolytes 1-1, AgNO₃, LiNO₃ et KNO₃ en solution eau-éthanol et AgNO₃, KNO₃, NaCl, KCl, RbCl et LiCl en solution eau- dioxanne. L’homogénéité des k_A calculés a été contrôlée en dressant la courbe log k_A en fonction de 1/D. On compare également ces valeurs aux valeurs de conductance fournies par Fuoss.
