The electrochemical behaviour of the Cd electrode in O-1-6 N NaOH has been investigated. Both the potentiostatic and galvanostatic techniques were employed. It has been shown that the electrode surface is primarily covered with a porous layer of Cd(OH), which is precipitated from the solution. Above

Zinc dissolution and passivation in either arsenate or borate and a mixture of arsenate-borate solutions at pH 8.9 was studied by polarization curves and cyclic voltammetry. The arsenate anion produces an increase on zinc dissolution . Potential sweep rate, rotation speed, temperature, dissolved oxy
Steady-state polarization curves and impedance data have been obtained for the electrochemical dissolution of copper in 1.0 M Na,SO, solutions at pH 1, 2, $4 and 5. The steady-state polarization curves display only active dissolution in the potential range investigated (from the open circuit potenti
Al~traet--Two main views are found in the literature regarding the type of oxide formed on copper anodes in alkaline solutions. The one considers that copper oxidizes to Cu~O and CuO (or Cu(OH),) before oxygen evolution. Mftller is, however, of the opinion that a still higher oxide, Cu~O,, forms. Th
