Abstract
The complexation of copper(II) with thiosemicarbazide (Tsc) in aqueous solution at t = 25°С (in 0.1 М HClO4 and 1.0 М HCl) was studied by potentiometry and spectrophotometry. It was found that in 0.1 М HClO4 and 1.0 М HCl, stable thiosemicarbazide complexes CuTsc\(_{2}^{{2 + }}\) formed at a ratio of СTsc/\(C_{{{\text{Cu}}}}^{{2 + }}\) ≥ 2.0. In hydrochloric acid, stepwise replacement of ligands occurs according to the equation [CuClx]\(^{{ + 2-x}}\) + iTsc = [CuCl\({{_{x}}_{{-1}}}\)Tsci]\(^{{ + 2-(x-1)}}\) + xCl–, βi. The stability constants of thiosemicarbazide and chloro thiosemicarbazide copper(II) complexes calculated from spectrophotometric data are \(\log {{\beta }_{1}}\) = 3.96 ± 0.10, \(\log {{\beta }_{2}}\) = 8.01 ± 0.10 (0.1 М HClO4); \(\log {{\beta }_{1}}\) = 4.19 ± 0.06, \(\log {{\beta }_{2}}\) = 7.87 ± 0.08 (1.0 М HCl).
