For the amalgam the value is ~ 60 mV not 9 mV as shown earlier 1. The discrepancy is due to the lack of reversible behaviour of the Zn(Hg)/ZnO electrodes.

As a preliminary stage in the study of the active~passive transition on zinc in concentrated (6.8 mol dm-3) solutions of KOH the reported mechanisms have been reviewed and the characteristics of active dissolution prior to passivation have been investigated. The theory of Armstrong and Bulman has be
The anodic dissolution and passivation of vertical porous zinc electrodes that were prepared by pressing zinc powder or amalgamated zinc powder into small disks were studied in 6 M KOH + O-25 M ZnO by measuring potentiostatic current/potential curves at a rate of 1 mV/s and by taking photomicrograph
