5a. The Extraction of Lead. Because its position in the reactivity series of metals, lead can be extracted using carbon (coke) in a smelting furnace.Because lead is below carbon, that is less reactive than carbon, lead can be displaced by carbon from lead oxides or lead sulfides in a sort of displacement reaction. The principal ore of lead is galena, chemical formula PbS lead sulphide (lead(II ...

1. Action of air:-. Dry air has effect on zinc but in moist air, zinc forms a protective layer of basic zinc carbonate. Zn + O 2 + H 2 O + CO 2 → ZnCO 3 .Zn (OH) 2. When heated in air, zinc burns greenish blue flame forming clouds of light, white power of zinc oxide which is commonly known as ‘philosopher’s wool.
