Abstract
Precise electrical conductance measurements are reported for some ethanoates, viz. ammonium, lithium, sodium and potassium in pure tetrahydrofuran (THF) and dimethyl sulfoxide (DMSO) and their binary mixtures at 298.15K. The conductance data have been analyzed by the Fuoss conductance–concentration equation to evaluate the limiting molar conductance (Λo), the thermodynamic association constant (KA) and the association diameter (R) for ion-pair formation. The limiting ionic conductances have been estimated from the appropriate division of the limiting molar conductivity value of the “reference electrolyte” Bu4NBPh4. Furthermore, the conductance data for pure THF have been analyzed by the Fuoss–Kraus theory of triple ions and the values of the ion-pair and triple-ion formation constants (KP and KT) were made and the results have been discussed in terms of molecular scale model.
