The equilibria of the complex formation between AuCl4-n(OH)(n)(-) and I- was studied spectrophotometrically in aqueous solutions containing KI:Au(III)less than or equal to 2 in the acidity range from 1 M HCl to pH 7 at 25 degrees C, From the hydrogen ion and Cl- ion dependence of the absorption spectra, it was found that AuCl(2)l(2)(-) and Au(OH)(2)I-2(-) complexes were formed. The equilibrium constants of complex formation were determined.
