Chemical Properties Of Aluminum

Chemical properties of aluminum: aluminum is active metal, in the dry air aluminum surface immediately formed about 50 angstrom (1 angstrom =0.1 nanometer) dense oxide film, so that aluminum will not be further oxidized and water resistant; But aluminum powder, when mixed with air, burns easily; Molten aluminum can react violently with water; Aluminum is amphoteric and soluble in strong bases as well as dilute acids.

Aluminum is a kind of metal element, the element symbol is Al, is a kind of silver white light metal. It's malleable. Commodities are often made in rod, flake, foil, powder, ribbon and filamentous form. In the humid air can form a layer of oxide film to prevent metal corrosion. The aluminum powder burns violently with heat in the air and emits a blinding white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water.
