Electrical conductance and ion pair formation of Co [III] complexes of acetylpyridinethiosemicarbazone halides in ethanol-water mixtures at 25C

The conductance of [III] complexes of acetylpyri-dinethiosemicarbazone halides were measured in ethanol-water mixtures covering a range of dielectric constant 24.33 < D < 78.54 at 25C. The conductance parameters derived from the Fuoss-Onsager conductance theory indicate that the solvation of these halides decreases with the decrease of the dielectric constant until a certain minimum and then increases again. The plots of log Ka vs. 1/D are not linear indicating that the solvent separated-ion pairs in these systems are characterized by strong hydrogen bonding

Electrical conductance of co [III] complexes of acetylpyridine-Thiosemicarbazone halides in aqueous solutions at 25 C

The conductance of Co [III] complexes of acetylpyridine- thiosemicarbazone halides has been measured in water at 25C and the data are analyzed using the Fuoss-Onsager equation for 1: 1 associated electrolytes. The characteristic functions, lambda o, a 0 and KA were derived and the association constant KA was analyzed on the basis of the solvent separated-ion pair model
