These are iron oxides, especially ferrous oxide (wüstite FeO) and ferric oxide (hematite Fe 2 O 3) or their mixture magnetite (ferroferric oxide Fe 3 O 4). The bottom layer consists of wüstite, which is relatively soluble in the pickling solution. It is usually covered by a layer of less soluble magnetite or very poorly soluble hematite.

Both of these compounds are ferrous oxides. Therefore, Fe 2 O 3 can be given as a simple oxide, where Fe in Ferric oxide results in only +3 in the oxidation state, and hence, Fe 3 O 4 is a mixed oxide, where the Fe in Ferrous oxide exists in both +2 and +3 oxidation states. Although, we can compose Fe 3 O 4 as FeO. And, Fe 2 O 3 can be written as iron oxide (II), whereas, Fe 3 O 4 can be ...
