Abstract The conductance of tetrabutylammonium nitrate, perchlorate, and picrate and of tetraethyl-, tetrapropyl-, and tetrabutylammonium tetraphenylborides has been measured at 25°C ini-butyronitrile and in mixtures of this solvent with benzene, carbon tetrachloride, dioxane, and tetrahydrofuran, covering the range of dielectric constants 10–23.81. The association constant for a given salt is the same in isodielectric mixtures ofi-butyronitrile with the nonpolar liquids; association is greater at a given dielectric constant for the mixtures with tetrahydrofuran. Single-ion mobilities are specific for any ion-solvent combination and therefore cannot be described in terms of the radius of an equivalent sphere and the bulk dielectric constant and viscosity of the solvent.
