✦ Synopsis

Molar conductivities were measured at 298.15 K for symmetric quaternary ammonium picrates, R,NPic, with R equal to C, to Cs as well as for potassium picrate in propylene carbonate. The molar conductivities at infinite dilution, association constants of ion pairs, ionic conductivities at infinite dilution, and Stokes radii were calculated for the ions employed. The salts, Me,NPic and Et,NPic, were found to be dissociated, the others are associated. For the associated salts the data conform to the Fuoss model for the association process.
