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.

β¦ Synopsis
For example, in the classical work of Landsberg and Bartelt 1, the equation (i-i~)r~ = k indicates that below i I the electrode will not passivate owing to the mass transfer limitations in solution, i~ is the current density equivalent to transfer of mass from the electrode by processes other than diffusion.

AImract--Galvanostatic experiments have been made on iron electrodes in hydrogen-poor and hydrogen-saturated alkaline solutions at 20Β°C. Emphasis was on the active behaviour of iron, but attention was also paid to its passivation. The mechanism of the anodic dissolution of active iron is found to b
