WebApr 6, 2024 · Lead (IV) oxide is an inorganic compound which is amphoteric in nature and has an oxidation state of +4. Lead dioxide exists in two major polymorphs, they are alpha and beta, which occur naturally as rare minerals scrutinyite and plattnerite. It is insoluble in water and alcohol and soluble in acetic acid. It decomposes when it is heated in air. WebOxidizing agents in water, such as dissolved oxygen, can react with exposed lead pipes causing soluble Pb2+ ions to enter the sup-ply. Two chemical reactions are involved: 1) oxidation, and 2) reduction. Both reactions are called redox reactions, for short.
