Abstract

Substitution of chloride ions in AuCl −4 with ethylenediamine (en) and propylenediamine (tn) is studied by capillary zone electrophoresis at I = 0.05 M and T = 25°C. The substitution constants are determined: AuenCl +2 + en = Auen 3+2 + 2Cl–, logK2 = 10.4; AuCl −4 + tn = AutnCl +2 + 2Cl–, logK1 = 16.1; AutnCl +2 + tn = Autn3+2 + 2Cl–, logK2 = 12.0.
