Abstract
Substitution of chloride ions in AuCl4− 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: AuenCl2+ + en = Auen23+ + 2Cl–, logK2 = 10.4; AuCl4− + tn = AutnCl2+ + 2Cl–, logK1 = 16.1; AutnCl2+ + tn = Autn3+2 + 2Cl–, logK2 = 12.0.
