Abstract
- Conductance data for NaNO3, KI, Pr4NBr and Bu4NI in N,N-dimethylformamide (DMF) at − 40, − 35, − 25, − 15, − 5, 5, 15, 25, 35 and 45°C are reported. The data have been analysed by the Lee–Wheaton conductance equation in terms of the limiting molar conductance (Λ0) and association constant (KA). Evaluation of single ionic conductances has been carried out on these data and on preceding experimental conductance data for MBr (M = Na+, K+, Cs+, NH4+, Et4N+, Pr4N+, Ph4P+), KClO4, NaBPh4 , Ph4PCl and Bu4NBPh4 using the Walden product of Bu4N+. The temperature dependences of Λ0 and KA are discussed. The values of KA indicate that all these salts are weakly associated in DMF.
