Abstract:
Density, viscosity, and conductance of the salts NaClO4, NaSCN, CF3SO3Na, CH3SO3Na, NaBPh4, and i-amyl3BuNBPh4 in dimethyl sulfoxide DMSO were determined over a concentration range 0.0001 mole1 to near saturation and a temperature range 25 to 55C. Conductance data were analyzed by the Fuoss-Onsager conductance equation. Limiting ionic mobilities for the ions at infinite dilution were obtained as a function of temperature assuming equal limiting mobilities for i-amyl3BuN and BPh4- ions in DMSO. Comparison of the effective ionic radii with crystallographic radii shows that the Na ion is solvated with two DMSO molecules while the i-amyl3BuN ion and the anions are relatively unsolvated. The effective ionic radii in DMSO are insensitive to temperature over the temperature range studied. Activation energies for ionic conductance in dilute solutions of i-amyl3BuNBPh4, NaBPh4, NaClO4, CF3SO3Na, and NaSCN are reported. Ionic transport in DMSO appears to be limited principally by viscous drag. Author
