What is Lead(II) sulfide?
[[File:Sulfid olovnatý.PNG|thumb|Lead(II) sulfide]] '''Lead(II) sulfide''', also known as '''plumbuus sulfide''', is a [[chemical compound]]. Its chemical formula is PbS. It contains [[lead]] and [[sulfide]] [[ion]]s. The lead is in its +2 [[oxidation state]]. ==Properties== Lead(II) sulfide is a black solid. It does not react with [[acid]]s. It reacts with air at a high temperature to make [[lead(II) oxide]]. It is one of the least toxic forms of lead. This does not mean that it is not toxic, though. It is the result of a test for hydrogen sulfide. Paper soaked in lead(II) acetate is passed through hydrogen sulfide. The colorless lead(II) acetate turns black. ==Preparation== It can be made by reacting [[hydrogen sulfide]] with [[lead(II) acetate]] or [[lead(II) nitrate]]. This makes a black solid. ==Occurrence== It is found as the [[mineral]] [[galena]]. Galena is a little shinier. ==Uses== It was once used as a black pigment. Now it is mainly used in [[infrared detector]]s. ==Related pages== *[[Lead(II) chloride]] *[[Lead(II) sulfate]] [[Category:Lead compounds]] [[Category:Sulfur compounds]]
