Lead Quick inquiry Where to buy Suppliers range | Lead. Uses: The metal is not attacked by hot water. But in the presence of free oxygen, lead(II) hydroxide is formed. The overall reaction is: 2Pb + 2H2O + O2 ? 2Pb(OH)2 In hard water, however, the presence of small amounts of carbonate, sulfate, or silicate ions form a protective film on the metal surface, and prevent the occurrence of the above reaction and thus, corrosion of the metal. Lead does not evolve hydrogen readily with acids. Nitric acid attacks the metal readily, forming lead nitrate and oxides of nitrogen: 3Pb + 8HNO3 ? 3Pb(NO3)2 + 2NO + 4H2O This reaction is faster in dilute nitric acid than strong acid. Hydrochloric acid has little effect on the metal. At ordinary temperatures, lead dissolves slowly in hydrochloric acid, forming a coating of lead(II) chloride, PbCl2 over the metal, which prevents further attack. At ordinary temperatures, lead is not readily attacked by sulfuric acid. A coating of insoluble lead sulfate formed on the metal surface prevents any further reaction of the metal with the acid. The acid is, therefore, stored in specially designed lead containers. Also, the action of hot concentrated sulfuric acid is very low up to about 200°C. However, at temperatures near 260°C, both the concentrated sulfuric and hydrochloric acids dissolve lead completely. At ordinary temperatures, hydrofluoric acid also has little action on the metal. Formation of insoluble PbF2 prevents dissolution of lead in the acid. Organic acids in the presence of oxygen react slowly with lead, forming their soluble salts. Thus, acetic acid in the presence of oxygen forms lead(II) acetate: 2Pb + 4CH3COOH + O2 ? 2Pb(CH3COO)2 + 2H2O Lead dissolves in alkalies forming plumbite ion, Pb(OH)42¯ with the evolution of hydrogen: Pb + 2OH¯ + 2H2O ? Pb(OH)42¯ + H2 Lead combines with fluorine, chlorine, and bromine, forming bivalent lead halides: Pb + Cl2 ? PbCl2 Fusion with sulfur at elevated temperatures yields lead sulfide, PbS. The metal is oxidized to PbO when heated with sodium nitrate at elevated temperatures. Pb + NaNO3 ? PbO + NaNO2 Lead is widely used in storage batteries. Each cell consists of a spongy lead plate as cathode and lead dioxide as anode immersed in the electrolyte sulfuric acid. The overall chemical reaction in the cell during discharge is as follow | |
Lead(II) carbonate Quick inquiry Where to buy Suppliers range | Lead(II) carbonate. Uses: When heated at 315°C, lead carbonate decomposes to lead oxide and carbon dioxide: PbCO3?PbO + CO2 When heated in water, it transforms to basic lead carbonate, 2PbCO3 Pb(OH)2 3PbCO3 + H2O ? 2PbCO3 Pb(OH)2 + CO2 Lead carbonate dissolves in acids, forming the corresponding lead salt and evolving carbon dioxide: PbCO3 + 2HCl ? PbCl2 + H2O + CO2 Reaction with concentrated acetic acid yields anhydrous lead(II) acetate. Fusion with boric acid at high temperature forms lead metaborate that has an approximate composition Pb(BO2)2 H2O. The product loses water of crystallization at 160°C.

Lead(IV) acetate Quick inquiry Where to buy Suppliers range | Lead(IV) acetate. Uses: Lead tetraacetate, on treatment with water, hydrolyzes to lead dioxide and acetic acid: Pb(CH3COO)4 + 2H2O ?
