Iron(III) chloride describes the inorganic compounds with the formula FeCl3(H2O)x. Also called ferric chloride, these compounds are available both in an anhydrous and hydrated forms. They are common source of iron in the +3 oxidation state. The hydrate and the anhydrous derivative have distinct properties. See more All forms of ferric chloride are paramagnetic, owing to the presence of five unpaired electrons residing in 3d orbitals. This electronic configuration places electrons in molecular orbitals that are antibonding … See more Water treatment In the largest application iron(III) chloride is used in sewage treatment and drinking water production as a coagulant and flocculant. In this application, an aqueous solution of FeCl3 is treated with base to form a See more The natural counterpart of FeCl3 is the rare mineral molysite, usually related to volcanic and other-type fumaroles. FeCl3 is also produced as an atmospheric salt aerosol by reaction between iron-rich dust and hydrochloric acid from sea salt.
