## Abstract The electrochemical behaviour of zinc in NaOH solutions has been investigated by using potentiodynamic technique and complemented by X‐ray analysis. The E/i curves exhibit active, passive and transpassive regions prior to oxygen evolution. The active region displays two anodic peaks. Th

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
