Reaction of iron with acids. Iron metal dissolves readily in dilute sulphuric acid in the absence of oxygen forming Fe (II) ions and H 2. In aqueous solution Fe (II) is present as the complex [Fe (H 2 O) 6] 2+. If oxygen is present, some of the Fe (II) oxidizes to Fe (III). Concentrated nitric acid, HNO 3, reacts on the surface of iron and ...

Nov 19, 2018 · Its chemical formula is often written Fe 3 O 4, but since it is a mixed oxide it is more correct to write FeO • Fe 2 O 3. Hematite or bloodstone ore, Fe 2 O 3, has acquired its name from the blood red streak that is formed when scratched. In Sweden, iron ore is mined in Kiruna and Malmberget by LKAB, which is Europe's largest iron ore producer.
