✦ Synopsis

Conductance data of triisoamylbutylammonium iodide, i-Am3BuNI (TABI) and sodium tetraphenylboride (NaBPIu) in the water+N,N-dimethylformamide (DMF), in the whole range of the mixed solvent composition at 298.15 K are reported. The data obtained have been analysed with the Fuoss-Justice equation in terms of the limiting molar conductance (Ao), ionic association constants (KA), and parameter R. Ionic association constant was found negligible for NaBPh4. From the data obtained here and those reported earlier, the individual limiting ionic conductivity of the Li ÷, Na +, K ÷, Rb ~, Cs ÷, Me4N ÷, Et4N ÷, Pr4N +, Bu4N +, I-Iex4N ÷, i-Am3BuN +, and of CI, Br, I, Ph4B has been determined using Fuoss-Hirsch assumption. From the values of the individual limiting ionic conductance obtained in this manner, the values of the Walden products for single ions were also calculated. The results obtained here as well as the values of the limiting molar conductance and Walden products for individual ions have been discussed.
