WebIn chemistry, iron(III) refers to the element iron in its +3 oxidation state.In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) denoted by Fe 3+.. The adjective ferric or the prefix ferri- is often used to specify such compounds — as in "ferric chloride" for iron(III) chloride, FeCl 3.The adjective "ferrous" is used instead for iron(II) … Iron shows the characteristic chemical properties of the transition metals, namely the ability to form variable oxidation states differing by steps of one and a very large coordination and organometallic chemistry: indeed, it was the discovery of an iron compound, ferrocene, that revolutionalized the latter field in the 1950s. Iron is sometimes considered as a prototype for the entire block of transition metals, due to its abundance and the immense role it has played in the …
