The conductance behavior of potassium picrate, salicylate, bromide, and iodide as well as tetraethylammonium bromide and tetrabutylammonium tetraphenylboride and iodide has been studied at x = 0.20, 0.40, 0.60, and 0.80 (at 25 degree C) and 1.0 (at 30 degree C) for mixtures of x sulfolane + (1 - x) water. The conductance data are organized and treated on the basis of the Fuoss (1978) equation using the Fuoss computer program. Values of the limiting molar conductance ( Lambda sub(0)), association constant (K sub(A)), and cosphere diameter (R) are obtained as a result of the treatment. The limiting ionic mobilities of the individual ions have been reported on the basis of tetrabutylammonium tetraphenylboride reference electrolyte. The Walden product for each system interestingly showed maxima and minima at different mole fractions of sulfolane studied.
