• Electrode effects on temporal changes in electrolyte pH ...

    Iron dissolution is the governing reaction at the anode of iron electrodes and ferrous ions (Fe 2+) are produced as main product. The main cathodic reaction is water reduction that is same for iron and inert electrodes. The oxidation rates of iron and the flux of ferrous ions per electrolyte volume are controlled by the electric current.

    The mechanism of the electrolytic reduction is probably similar to that of Clemmensen reduction, which starts from anion radical formation by one-electron transfer, as indicated in Scheme 3. The difference is that electrolytic reduction takes place in an electric double layer, rather than on the surface of the zinc metal.
