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 ...
Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of sodium bicarbonate, an inert electrolyte, with an iron anode: 4 Fe + 3 O 2 + 2 H 2 O → 4 FeO(OH) The resulting hydrated iron(III) oxide, written here as FeO(OH), dehydrates around 200 °C. [18] [19] 2 FeO(OH) → Fe 2 O 3 ...
Iron(III)-hydroxide polymaltose complex is a medication used to treat iron deficiency / iron deficiency anemia and belongs to the group of oral iron preparations.The preparation is a macromolecular complex, consisting of iron(III) hydroxide (trivalent iron, Fe 3+, Fe(OH) 3 ·H 2 O) and the carrier polymaltose and is available in solid form as a film-coated or chewable tablet and in liquid form ...

Iron(II,III) oxide, or black iron oxide, is the chemical compound with formula Fe 3 O 4. It occurs in nature as the mineral magnetite . It is one of a number of iron oxides , the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3 ) which also occurs naturally as the mineral hematite .
Iron dissolved in groundwater is in the reduced iron II form. If this groundwater comes in contact with oxygen at the surface, e.g. in natural springs, iron II is oxidised to iron III and forms insoluble hydroxides in water. [7] The natural analogue of iron(II) hydroxide compound is the very rare mineral amakinite, (Fe,Mg)(OH) 2. [8] [9]
