Study of Silver(I) Complex Formation with Some Thiourea Derivatives in Aqueous Solution

Abstract: The equilibrium processes of the formation of mononuclear and some binuclear silver(I) complexes with thiourea, N-acetylthiourea, thiosemicarbazide, N-phenylthiourea, and N,Nʹ-diphenylthiourea at 25°C and I = 0.11 M. (0.01 M HNO3 + 0.1 M NaNO3) in aqueous solution were studied by potentiometry method with a silver electrode. The stability constants of the complexes were determined. The stability of mononuclear complexes is almost identical for all the ligands, except for complexes with acetylthiourea, for which it is lower. © 2020, Pleiades Publishing, Ltd.
