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

Precise conductance measurements of solutions of tetrabutylammonium bromide (Bu4NBr), sodium tetraphenylborate (NaBPh4), 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 (Lambda(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 Bu4NBPh4. 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.
