Lead(II) phosphate
Lead phosphate is an ionic compound with chemical formula Pb32. Lead phosphate is a long-lived electronically neutral reagent chemical. Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA. Lead phosphate appears as hexagonal, colorless crystals or as a white powder. Lead phosphate is insoluble in water and alcohol but soluble in HNO3 and has fixed alkali hydroxides. When lead phosphate is heated for decomposition it emits very toxic fumes containing Pb and POx.
It is prepared by reacting lead acetate with sodium orthophosphate.
