Abstract
Stepwise substitution equilibria of ligands in the system of gold(I) sulfite-thiosulfate complexes in an aqueous solutions, namely Au(SO3)23- + S2O32-= Au(SO3)(S2O3)3- + (logß1 = -0.35 ± 0.15) and Au(SO3)23- + S2O32- = Au(S2O3)23-(S2O3)3-(logß2 = -0.99 ± 0.05), were studied at 25°C and I = 1 M (NaCl). The UV spectra of these species were recorded. The method of taking into account the systematic effect of sulfite oxidation by air oxygen with the use of independent series of measurements under conditions close to the conditions of main experiments was tested.
