Abstract

The effect of concentrated uni-univalent electrolytes on the oxidation kinetics of sulfur in the chelate ligands (-SCH<sub>2</sub>CH<sub>2</sub>NH<sub>2</sub>-)<sup>-</sup>, (-SOCH<sub>2</sub>CH<sub>2</sub>NH<sub>2</sub>-)<sup>-</sup>, (-SCH<sub>2</sub>COO-)<sup>2-</sup>, and (-SOCH<sub>2</sub>COO-)<sup>2-</sup> bound in Co(III) complexes with various oxidants (H<sub>2</sub>O<sub>2</sub>, IO<sub>4</sub><sup>-</sup>, S<sub>2</sub>O<sub>8</sub><sup>2-</sup> has been studied at 298.2 K. The results show that the changes observed in the rate constants are due to interactions between the supporting electrolyte and solvent.
