Electrical Conductances of Tetrabutylammonium Bromide, Sodium Tetraphenylborate, and Sodium Bromide inN,N-Dimethylformamide at (308.15, 313.15, 318.15, and 323.15) K

Precise conductance measurements of solutions of tetrabutylammonium bromide (Bu 4 NBr), sodium tetraphenylborate (NaBPh 4 ), and sodium bromide (NaBr) in N, N -dimethylformamide have been reported at (308.15, 313.15, 318.15, and 323.15) K. The conductance data have been analyzed by the 1978 Fuoss conductance−concentration equation in terms of the limiting molar conductance (Λ 0 ), the association constant ( K A ), and the association diameter ( R ). The limiting ionic conductances have been estimated from an appropriate division of the limiting molar conductivity of the “reference electrolyte” Bu 4 NBPh 4 . Slight association was found for all these salts in this solvent medium. The limiting molar conductances of electrolytes as well as single-ion conductivity values increase appreciably with temperature.
