Iron (III) oxide Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare, and iron(II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe2O3 is the main source of iron for the steel industry. Fe2O3 is ferromagnetic, dark red, and readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition.

What Does FE (CLO3)3 Mean? Quick Answer. In chemistry, Fe(ClO3)3 is the molecular formula for the compound iron(III) chlorate. The formula uses symbols to represent each element in the compound, with Fe for iron, Cl for chlorine and O for oxygen. In a chemical formula, the number directly after the element indicates the number of atoms of that element in a single molecule of the compound.

- That the ratio (iron atoms)/(oxygen atoms) is 4/6, or 2/3, and nothing else is an example of the law of definite proportions. If iron is heated in the presence of less oxygen, it is possible to synthesize another iron oxide, Fe 3 O 4, called magnetite. This is the magnetic loadstone known for centuries as a naturally occurring mineral. It is black in color, and its balanced net synthesis reaction is.

- Fe. The most stable oxidation states of iron are Fe(III) and Fe(II). Fe(III) ions form yellow or brown (rusty!) or red compounds with various agents. The reaction with thiocyanate ion is among the best for Fe(III) determination: Fe3+ + 3 SCN-Fe(SCN)3 Fe3+: To a drop of unknown solution, add several drops of NH4SCN.

- Rust is really Fe2O3, a reddish form of iron oxide. Iron has another oxide, Fe3O4, which is sometimes called black oxide, black rust, or hammerscale. Black oxide is a good protection for steel. Like aluminum oxide, black oxide molecules are the same size as iron molecules, so black oxide does not grow or flake.

Chemistry help! Oxidation state of iron? Chemistry help! Oxidation state of iron? K3[Fe(C2O4)3] is neutral. C2O4 is 2-, so (C2O4)3 is 6-. K3 is 3+. So the Fe must be 3+ to make it all come out zero. The permanganate reacts with the oxalate, not the iron, so the iron remains at 3+ throughout.
