Abstract:	We have developed a model for the anodic dissolution and passivation of the zinc electrode in alkaline electrolyte. The model is based on postulated elementary reactions. Species on the electrode surface are assumed to follow Langmuir behavior. In previous work we proposed a model for the dissolution kinetics in the prepassive region. In the present investigation we have extended this model to include the passivation process. Using our model, we are able to simulate the general features of the current‐potential behavior. Effects of hydroxide concentration and mass transport rates on current‐potential curves are qualitatively predicted by the model.
