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.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
