What is Lead arsenate?
'''Lead arsenate''' is a [[chemical compound]]. Its chemical formula is PbHAsO<sub>4</sub>. It has [[lead]], [[hydrogen]], and [[arsenate]] (HAsO<sub>4</sub><sup>2-</sup>) [[ion]]s in it. The [[lead]] is in its +2 [[oxidation state]]. ==Properties== Lead arsenate is a white solid. It is highly [[toxic]] because of the lead and the [[arsenic]] in it. It does not dissolve in water. ==Preparation== It was made by reacting [[lead nitrate]] with [[arsenic acid]]. ==Uses== It was the most used [[insecticide]] that had arsenic in it. It was used against the [[potato beetle]] and the [[spongy moth]]. It replaced the even more toxic [[Paris Green]]. It was later used to kill certain [[moth]]s, [[mosquito]]es, and pests of [[cranberry|cranberries]]. It was found that it stayed inside fruits even after washing off, so it was replaced with [[DDT]]. It was completely banned in 1988. ==Related pages== *[[Lead chloride]] *[[Potassium arsenate]] *[[Sodium arsenite]] [[Category:Lead compounds]] [[Category:Arsenic compounds]]
