Conductances of the solutions of silver acetate in 10 to 90% (w/w) acetonitrile–water mixtures were measured at 25 °C. The molar conductances at infinite dilution and association constants were calculated, using the Fuoss-Hsia equation with Fernandez-Prini coefficients. There was no association in 10 and 20% acetonitrile. The log<I>K</I><SUB>A</SUB> <I>vs.</I> 1/D plot was a straight line with negative intercept in accordance with the modified Denison-Ramsey theory of ion-pair formation. Walden products were also calculated. From these results it was concluded that silver ions are preferentially solvated by acetonitrile whereas acetate ion is hydrated in acetonitrile–water mixtures.
