Abstract

The cathodic reduction of the [Au(SO₃ )₂]^3- complex was investigated in the pH region 6.5 - 9.5. Two distinct reduction mechanisms were evidenced. Thus, in neutral solutions, the gold complex is probably reduced chemically by dithionite ion which is formed cathodically by reduction of bisulfite ion. In alkaline media, direct cathodic reduction of the complex takes place.
