Abstract
A functional dependence of the potentiostatic dissolution rate of iron on the metal surface coverage with hydrogen (θ) is found. An increase in the anodic current with time after the potential jump is related to the decrease in θ. A potential dependence of the dissolution rate of iron at θ = const is obtained. The high Tafel slope of this polarization curve shows that the first one-electron stage of iron ionization is substantially irreversible.
