Popis:	Gold dissolves anodically in acetonitrile solutions containing dissolved NaSCN, at 25°C. The reaction yields Au(I) and Au(III) complex ion species which can be cathodically electroplated. The voltammetric experiments indicate that the anodic dissolution is preceded by a partial surface saturation with the intermediate initially discharged, followed by a diffusion controlled process which depends on the SCN − ion concentration. The electrochemical behaviour of the anodic and cathodic processes is comparable to that of gold in aqueous solutions containing Au-complex ions.
