Conductometric Study of Ion-Ion and Ion-Solvent Interactions. I. Conductances of Silver Acetate in 0–50% (w/w) Methanol–Water Mixtures at 35 °C

Abstract

Abstract Conductances of the solutions of silver acetate in 0 to 50% (w/w) methanol–water mixtures were measured at 35 °C. The association constants and molar conductances at infinite dilution were calculated using the Shedlovsky extrapolation technique and the Fuoss-Hsia equation with Fernandez-Prini coefficients. The logKA vs. 1⁄D plot passes through the origin in accordance with the Denison-Ramsey theory of ion-pair formation. The results were interpreted in terms of the equilibrium between the solvent separated ion-pairs (SSIP) and contact ion-pairs (CIP).
