There are several oxidation reactions of iron


Since iron has two valence states: +2 iron is called ferrous, +3 iron is called iron, so iron oxide is +3, and since oxygen is -2, according to the formula, the formula is Fe2O3. Iron oxide is the main component of rust. The leading cause of rust is that iron metal reacts with water and oxygen in the environment in the presence of carbon impurities, and iron metal rusts. For paint, ink, rubber, and other industries, it can be used as catalysts, glass, gems, and metal polishing agents and can be used as iron-making raw materials. The most significant use of iron oxide is as a pigment. The color is divided into iron oxide red, iron oxide yellow, iron oxide black, iron oxide brown by iron oxide red, and iron oxide black (and iron oxide yellow) mixed; Iron oxide orange is a mixture of iron oxide red and iron oxide yellow; Iron oxide green is a mixture of blue phthalocyanine blue and iron oxide yellow. When the iron oxidizes, it doesn't disappear; it forms iron trioxide, which means the iron rusts. And ferric oxide is a reddish brown powder, insoluble in water, organic acids, and organic solvents. It was dissolved in inorganic acid. And there are two types: α-type (positive magnetism) and γ-type (diamagnetism).

Iron oxidation is a chemical reaction. When iron is left for a long time, it oxidizes and rusts. In addition to its chemical activity, iron is easy to rust and has much to do with external conditions. And water is one of the things that makes iron easy to rust. Only water, however, does not cause iron to rust. Only when oxygen in the air is dissolved in water does it react with iron in the presence of water?
