Conductance of quinolinium dichromate has been measured in water and N,N-dimethyl formamide mixtures over the complete compositional range. The limiting molar conductance Lambda(o) and the association constant of the ion pair, K(A), have been computed using the Shedlovsky equation. Lambda(o) increases with an increase in the proportion of water in the solvent mixture. The Kraus-Bray equation has also been used to correlate the limiting molar conductance data, and the dissociation constant of the ion pair, K(C), has been computed. The results have been discussed in terms of ion-solvent interactions.
