lead
Elemental lead can also be oxidized to the Pb 2+ ion by hydrogen ions but the insolubility of most salts of Pb 2+ makes lead resistant to attack by many acids Oxidation under alkaline conditions is easier to effect and is favoured by the formation of the soluble species of lead in the +2 oxidation state
