Pseudo steady-state current-potential measurements have been made during the dissolution and passivation of zinc electrodes in 6.8 mol dm-3 (30 ~o w/w) KOH solutions over a wide potential range. The pre-passive characteristics are very sensitive to impurities, viz. iron. Similarly, ir drop has an ap
