The following Figure illustrates the E-pH diagram for iron in the presence of water or humid environments at 25 o C, which was calculated by considering all possible reactions associated with iron in wet or aqueous conditions listed in the Table below, excluding therefore drier forms of corrosion products such as magnetite (Fe 3 O 4) or iron (ferric) oxide (Fe 2 O 3).

In order to add this variable, we must expand the predominance diagram to include the reduction potential of the environment as well as the pH.
