Conductance of cobalt [II] complexes of acetonethiosemi-carbazone chloride and bromide in methanol-water mixtures at 25

ABSTRACT

The conductance of cobalt [II] complexes of acetone thiosemicarbazone chloride and bromide is measured in methanol-water mixtures covering a dielectric constant ranging between 32.63 - 69.94 at 25C. The data are analyzed using the Fuoss-Onsager equation on an IBM-PC computer. It was found that a degree for chloride increase with the decrease of dielectric constant, while a degree for bromide decreases with the decrease of dielectric constant until a certain value, and then increases thereafter. The plot of log KA vs. 1/D is found to be nonlinear. Finally, the solvent separated-ion pair model is applied to these systems
