Reactive iron oxide

Iron oxides are chemical compounds composed of iron and oxygen. Several iron oxides are recognized. All are black magnetic solids. Often they are non-stoichiometric. Oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. Iron oxides and oxyhydroxides are widespread in nature and play an important … WebMay 21, 2024 · When Iron is left outside, overtime it reacts with oxygen to form Iron Oxide or rust. If you leave iron inside, this also happens because there is as much oxygen inside as outside. However, when it is wet and salty, the reaction proceeds at a higher rate, and it might be more humid and saltier outside (especially in the ocean).
