Gadolinium Quick inquiry Where to buy Suppliers range | Gadolinium. Uses: The only oxidation state known for this metal is +3. Therefore, all its compounds are trivalent. It reacts with dilute mineral acids forming the corresponding salts. The reaction is vigorous but usually not violent. 2Gd + 3H2SO4 ? Gd2(SO4)3 + 3H2 2Gd + 6HCl ? 2GdCl3 + 3H2 Although the metal is stable in air at ordinary temperature, it burns in air when heated at 150 to 180°C, particularly when present in sponge or powdered form having a large surface area. The product is gadolinium(III) oxide, Gd2O3. Gadolinium is a strong reducing agent. It reduces oxides of several metals such as iron, chromium, lead, manganese, tin, and zirconium into their elements. The standard oxidation potential for the reaction Gd ? Gd3+ + 3e- is 2.2 volts. Gadolinium burns in halogen vapors above 200°C forming gadolinium(III) halides: 2Gd + 3Cl2 ? 2GdCl3 When heated with sulfur, the product is gadolinium sulfide Gd2S3. Similarly, at elevated temperatures, gadolinium combines with other nonmetals such as nitrogen, hydrogen, and carbon forming nitride, hydride, and carbide respectively: 2Gd + N2 ? 2GdN 2Gd + 3H2 ? 2GdH3.

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 |
