Spectrophotometric investigations of the reaction between gold(III) and potassium iodide

Spectrophotometric investigations of the reaction between gold(III) and potassium iodide

The equilibria of the complex formation between AuCl4-n(OH)n- and I- was studied spectrophotometrically in aqueous solutions containing KI:Au(III)<2 in the acidity range from 1 M HCl to pH 7 at 25°C. From the hydrogen ion and Cl- ion dependence of the absorption spectra, it was found that AuCl2I2...
