What is Iron(II) oxide?
[[File:Iron(II) oxide.jpg|thumb|Iron(II) oxide]] '''Iron(II) oxide''' is an [[chemical compound]] composed of [[iron]] in the +2 [[oxidation state]] bonded to [[oxygen]] atoms. It easily converts to a mixture of iron and [[iron(II,III) oxide]] at room temperature. It is stable though when it is very hot. It is a black powder. If it gets hydrated (bonded to extra water molecules), it turns green. The green chemical, named [[iron(II) hydroxide]], gets [[oxidation|oxidized]] by oxygen to a reddish color of [[iron(III) oxide]]. Iron(II) oxide is very rare in nature because of how easily it converts to other [[iron oxide]]s. Natural samples are called '''wüstite'''. == Related pages == * [[Iron(II,III) oxide]] {{chem-stub}} [[Category:Iron compounds]] [[Category:Oxides]]
