| Abstract | Limiting molar conductances (Λ o ) of Ph 4 PBPh 4 , Bu 4 NBPh 4 , Bu 4 NNO 3 , Bu 4 NClO 4 , Bu 4 NBr, Bu 4 NI, Ph 4 PBr, NaBPh 4 , AgClO 4 , AgNO 3 , LiNO 3 , NaNO 3 , KNO 3 and NaBr have been determined in DMF-DMSO mixtures at 25, 35 and 45°C using Shedlovsky conductance equation. Limiting molar ionic conductances (λ o i ) have been calculated from λ o (Ph 4 P + ) ≅ λ o (Ph 4 B - ) assumption. Discussion of effective ionic radii (r i ) calculated from λ o i values is based on ion-solvent interactions. The results indicate the existence of electrostatic ion-solvent interactions in the case of alkali metal cations via O atom of both the solvents and specific interactions between Ag + ion and DMSO via S atom of S=O group of DMSO molecule. The latter is found to be in agreement with the concept of soft acid-base type of interactions. Association constants (K A ), however, yield no significant contribution. |
