What is iron III chlorate

Iron chlorides

Iron chlorides. Ferrous chloride, FeCl2 white, sublimable, very hygroscopic monoclinic prisms, D. 3.16 g cm-3, M.p. 674 ° C. FeCl is obtained2 by heating iron in a stream of hydrogen chloride or by reducing iron (III) chloride. The pale green dichlorotetraaquoeiron (II) hydrate [FeCl2(H2O)4] Â · 2H2O out. FeCl2 is used as a reducing agent, as a stain in dyeing and for pharmaceutical preparations.

Ferric chloride, FeCl3 dark green, reddish brown when viewed through, shiny metal, hexagonal crystals; D. 2.898 g cm-3, M.p. 306 ° C. FeCl3 is sublimable, at 400 ° C the vapor density corresponds to the formula Fe2Cl6, FeCl are at 800 ° C3Molecules. FeCl3 is in water as well as in organic solvents, e.g. B. ethanol, acetone or diethyl ether, readily soluble, hydrates crystallize from water; the iron (III) chloride of the trade is the yellow hexahydrate, which in the solid phase as a chloro complex [FeCl2(H2O)4] Cl · 2H2O, m.p. 37 ° C. FeCl reacts with chloride ions3 to chloro complexes [FeCl4]-, [FeCl6]3- and [Fe2Cl9]3-. FeCl3 is very hygroscopic and dissolves into an oily liquid (iron oil) in the air. FeCl suffers in aqueous solution3 Hydrolysis, whereby colloidal, red-brown iron (III) hydroxide Fe2O3  ·x H2O is formed. FeCl is obtained3 by passing chlorine over scrap iron at about 650 ° C, as a by-product of the chlorinating digestion of iron-containing oxidic ores. Its hydrates are obtained by reacting iron (III) oxide and hydrochloric acid. FeCl is used3 As a stain in dyeing and textile printing, as an oxidizing agent and chlorine carrier, in the processing of copper and silver ores, for the production of printed circuits, for etching copper gravure prints, in photo-engraving and for the production of ink. It is important in water treatment. Since FeCl3 Makes protein coagulate, cotton wool soaked with it serves to stop bleeding.
