    Liver of sulfur – formed by fusing [clarification needed] potash and sulfur. Lunar caustic/ lapis infernalis – silver nitrate, formed by dissolving silver in aqua fortis and evaporating. Lye – potash in a water solution, formed by leaching wood ashes. Potash – potassium carbonate, formed by evaporating lye; also called salt of tartar. K ...

  3. Iron(III) oxide - Wikipedia

    en.wikipedia.org/wiki/Iron(III)_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 ...

  4. Iron oxide - Wikipedia

    en.wikipedia.org/wiki/Iron_oxide

    An iron oxide is a chemical compound composed of iron and oxygen. Several iron oxides are recognized. Often they are non-stoichiometric.

  5. Ferrous - Wikipedia

    en.wikipedia.org/wiki/Ferrous

    Iron(II) chloride tetrahydrate, FeCl 2 ·4H 2 O. In chemistry, iron(II) refers to the element iron in its +2 oxidation state. The adjective ferrous or the prefix ferro-is often used to specify such compounds, as in ferrous chloride for iron(II) chloride (FeCl 2). The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+.

    en.wikipedia.org/wiki/Iron_compounds

    The iron compounds produced on the largest scale in industry are iron(II) sulfate (FeSO 4 ·7H 2 O) and iron(III) chloride (FeCl 3). The former is one of the most readily available sources of iron(II), but is less stable to aerial oxidation than Mohr's salt ((NH 4) 2 Fe(SO 4) 2 ·6H 2 O). Iron(II) compounds tend to be oxidized to iron(III ...

  7. Rust - Wikipedia

    en.wikipedia.org/wiki/Rust

    Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.

  8. Ferric - Wikipedia

    en.wikipedia.org/wiki/Ferric

    Potassium ferrioxalate contains the iron(III) complex [Fe(C 2 O 4) 3] 3−. In chemistry, iron(III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron(III) chloride (FeCl 3). The adjective ferrous is used instead for iron(II) salts, containing the cation Fe 2+.

  9. Green rust - Wikipedia

    en.wikipedia.org/wiki/Green_rust

    Green rust is a generic name for various green crystalline chemical compounds containing iron(II) and iron(III) cations, the hydroxide (OH −) anion, and another anion such as carbonate (CO 2− 3), chloride (Cl −), or sulfate (SO 2− 4), in a layered double hydroxide (LDH) structure. The most studied varieties are the following: [1]
