WebRusting is a complex reaction between iron, oxygen and water to form hydrated iron (III) oxides. Initially iron goes into solution as Fe 2+ ions, losing electrons: Fe (s) → Fe 2+ (aq) + 2e – This is oxidation and occurs on the iron where the protective oxide layer is weakest or damaged. Such areas are called anodic. WebRedox, rusting and iron - (CCEA) Oxidation is loss of electrons, gain of oxygen or loss of hydrogen.
