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
iron poisoning is an iron overload caused by a large excess of iron intake and usually refers to an acute overload rather than a gradual one. the term has been primarily associated with young children who consumed large quantities of iron supplement pills, which resemble sweets and are widely used, including by pregnant women; approximately 3 grams is lethal for a two-year-old.
ferricrete is a hard, erosion-resistant layer of sedimentary rock, usually conglomerate or breccia, that has been cemented into a duricrust by iron oxides. the iron oxide cements are derived from the oxidation of percolating solutions of iron salts.
there are sixteen known iron oxides and oxyhydroxides, the best known of which is rust, a form of iron iii oxide. iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. they are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes.
chakrabarti 1976 has identified six early iron-using centres in india: baluchistan, the northwest, the indo-gangetic divide and the upper gangetic valley, eastern india, malwa and berar in central india and the megalithic south india.

laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. nearly all laterites are of rusty-red coloration, because of high iron oxide content. they develop by intensive and prolonged weathering of the underlying parent rock. tropical weathering laterization is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils.
hemoglobin american english or haemoglobin british english / ˈ h iː m ə ˌ ɡ l oʊ b ɪ n, ˈ h ɛ-,-m oʊ-/ , abbreviated hb or hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells erythrocytes of almost all vertebrates the exception being the fish family channichthyidae as well as the tissues of some invertebrates.hemoglobin in blood carries oxygen .
although most compounds are referred to by their iupac systematic names following iupac nomenclature , traditional names have also been kept where they are in wide use or of significant historical interests.
