Lead - Wikipedia

Lead(II) oxide gives a mixed oxide on further oxidation, Pb 3 O 4. It is described as lead(II,IV) oxide, or structurally 2PbOPbO 2, and is the best-known mixed valence lead compound. Lead dioxide is a strong oxidizing agent, capable of oxidizing hydrochloric acid to chlorine gas. This is because the expected PbCl 4 that would be produced is unstable and spontaneously decomposes to PbCl 2 and ...

Extraction of lead from its ore This is done in two stages. Firstly the lead ore (which is mainly lead sulphide) is heated in air to oxidise it. The products are lead oxide and sulphur dioxide: 2PbS(s) + 3O2(g) 2PbO(s) + 2SO2(g) The lead oxide is then heated with coke (carbon) in a blast furnace to cause a displacement reaction which produces lead and carbon dioxide. This works because carbon ...
