Polarization curves for the anodic oxidation and cathodic reduction of Ni(OH), electrodes at constant current have been obtained, and also Tafel curves for the anodic process. A comparison is made between the electrochemical behaviour of freshly prepared and of recrystallized Ni(OH)2 layers, and the

The kinetics of polarographic reduction ofCo(II) and Ni(I1) has been investigated in the presence of increasing concentration of complex forming agent uiz wzaprolactam at pH 6.2 under constant ionic strength. In both the cases the waves were found to be diffusion controlled and irreversible. The val
