Conductance data are reported for Ph4AsPic, Ph4PPic, Ph4SbPic, Hex4NPic, Bu4PPic, Et4NSbCl6 in propylene carbonate at 25 deg C in the concentration range 1x10-4 to 15x10-4 M.The data were analyzed by the Justice modification of the Fuoss-Hsia equation and all salts studied were found to be associated and to form solvent separated ion pairs.Application of the Barthel-Bjerrum model of ion association permitted calculation of the non coulombic portion of the potentials of mean force, W+/-.Ionic limiting equivalent conductances of six ions were calculated using known values of R4N+, and Pic- ions.Walden products of ions in propylene carbonate were examined in the light of modern ion mobility theories, including Boyd-Zwanzig, Hubbard-Onsager, and Hubbard-Kayser models of ion solvent interactions.
