Polarographic Reduction of Monochloro-Pentammine Cobalt (Ill) Ion in Presence of Aminoacids

Polarographic reduction of monochloro-pentannnine cobalt (III) ion was carried out in strong sulphate medium in presence of various aminoacids which resulted in a positive shift in E_1/2 of the first reduction (Co^lll\(\to\) Co^ll) wave of the complex. These shifts in E_{\(\frac{1}{2}\)} values have been correlated with the substitution of aminoacids as a unidentate ligand in place of chlorine in the coordination sphere.
