Electrical conductance of cobalt [III] complexes of acetylpyridinethiosemicarbazone halides in ethanol at 25C

ABSTRACT

The conductance in ethanol solution of cobalt [III] complexes of acetylpyridinethiosemicarbazone halides has been measured at 25C and analyzed using the Fuoss-Onsager equation in an attempt to obtain accurate values of the molar specific conductivity at infinite dilution lambda degree, the closest distance of approach a degree and the association constant KA. From the study of the anion solvation, association was found to decrease with increasing the anionic radius. The relation between KA and the solvent separated-iron pair model was discussed. The electrostatic Stoke's radii R+ and R- were calculated
