The direct current conductivity of DMSO + KI solutions was determined with the use of the impedance spectroscopy. The measurements were performed in the whole solubility range of KI and in the temperature range from (293.15 to 323.15) K. The limiting molar conductivities ?o(T) and ?I o(T), as well as the constant KA of ionic association, K+ + I , were determined at different temperatures with the use of the Fuoss-Onsager method. The obtained data on KA, together with the literature data referred to the K+ + I association in different solvents, allowed us to formulate an empirical dependence of KA on the molecular dipolar polarizability of the solvent used, KA exp(-microi2), where microi is the dipole moment of the molecules of ith solvent.
