The polarographic and chronopotentiometric reduction of nickel(II) complexes

Abstract

A comparison of E_p reduction potentials with the absorption spectra and transition times of the complexes has proved valuable in the investigation of the reduction of nickel(II) complexes. From the work it can be stated that as the ligand in the complex becomes stronger (in the spectrochemical sense), the complex becomes more stable towards the mercury drop in that higher negative potentials are required for reduction and the chronopotentiometric rate of reduction becomes greater.
