Abstract: The electroreduction Co(III) + e^- reversible Co(II) of Co(III) complexes with neutral and anionic ligands (NH₃, H₂O, CO₃^2-, HCO₃^-, OH-) recorded as one polarographic wave is split into two waves in the presence of tetrabutylammonium ion. The first wave corresponds to the reduction of the Co(III) complexes only with neutral ligands and the second one (more negative) to the reduction of the Co(III) complexes with anionic ligands as well.
