What is Lead(II) oxide?
[[File:Lead monoxide.jpg|thumb|Lead(II) oxide]] '''Lead(II) oxide''', also known as '''plumbous oxide''' and '''litharge''', is a [[chemical compound]]. Its chemical formula is PbO. It has [[lead]] in the +2 [[oxidation state]]. It also contains [[oxide]] [[ion]]s. ==Properties== It is a yellow or red solid. When it is heated with charcoal it makes liquid [[lead]] metal. It is a [[crystalline]] solid. It is highly toxic since it has lead in it. It reacts with [[acid]]s to make other lead(II) salts and [[base (chemistry)|bases]] to make plumbites. ==Preparation== It can be made by heating lead strongly in air. It can be also made by heating [[lead carbonate]] or [[lead nitrate]]. ==Uses== It is made when lead is taken from its ores. The lead sulfide in [[galena]] is changed to lead(II) oxide, which is heated with charcoal to make liquid lead. It is used to make [[lead glass]]. It used to be used in lead paint. ==Related pages== *[[Lead(II) chloride]] *[[Lead(IV) oxide]] *[[Lead(II,IV) oxide]] [[Category:Lead compounds]] [[Category:Oxides]]
