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(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 oxides feature as ferrous or ferric or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, magnetite, and hematite. Oxides of Fe II. FeO: iron(II) oxide, wüstite; Mixed oxides of Fe II and Fe III. Fe 3 O 4: Iron(II,III) oxide, magnetite; Fe 4 O ...
Iron forms various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe 3 O 4), and iron(III) oxide (Fe 2 O 3). Iron(II) oxide also exists, though it is unstable at room temperature. Despite their names, they are actually all non-stoichiometric compounds whose compositions may vary. [12]
The chemical formula of iron sucrose is C 12 H 29 Fe 5 Na 2 O 23. The iron sucrose molecule is a polymer with two main molecules; sucrose (chemical formula C 12 H 22 O 11) and an iron (III) hydroxide (Na 2 Fe 5 O 8 •3(H 2 O)). These two components are in solution together, but are not bound to one another. [2]
Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle ironstone" [3]) but is more typically massive. [2]
