ABSTRACT

Equivalent conductivities of dilute solutions of calcium nitrate, cadmium nitrate, zinc nitrate, and calcium chloride (c less than 0.0021 eq *dm-3) were measured in binary aqueous mixtures containing up to 70 wt % cosolvent (methanol, ethanol, and acetone) at 298.15 K ( 0.1. Data were treated by the Fuoss-Edelson equation, and its parameters, the limiting equivalent conductivity, E0, and the primary association constants, K1A, were evaluated. Variations in Walden products and K1A were interpreted in terms of ionic properties as well as solvent structure and dielectric constant.
