Iron(III) phosphate, also ferric phosphate, [4] [5] is the inorganic compound with the formula Fe PO 4. Four polymorphs of anhydrous FePO 4 are known. Additionally two polymorphs of the dihydrate FePO 4 ·(H 2 O) 2 are known.
The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...

Iron(III) oxide-hydroxide or ferric oxyhydroxide [2] is the chemical compound of iron, oxygen, and hydrogen with formula FeO(OH). The compound is often encountered as one of its hydrates, FeO(OH) ·n H 2 O [rust]. The monohydrate FeO(OH) · H 2 O is often referred to as iron(III) hydroxide Fe(OH) 3, [3] hydrated iron oxide, yellow iron oxide ...
Ferric oxide, commonly called rust, is a very complicated material that contains iron(III). Iron(III) is found in many minerals and solids, e.g., oxide Fe 2 O 3 (hematite) and iron(III) oxide-hydroxide FeO(OH) are extremely insoluble reflecting their polymeric structure. Rust is a mixture of iron(III) oxide and oxide-hydroxide that usually ...

Iron(II) is oxidized by hydrogen peroxide to iron(III), forming a hydroxyl radical and a hydroxide ion in the process. This is the Fenton reaction. Iron(III) is then reduced back to iron(II) by another molecule of hydrogen peroxide, forming a hydroperoxyl radical and a proton.
