What Are The Chemical Properties Of Aluminum?

Aluminum is a reactive metal. In dry air, a dense oxide film of about 50 angstroms (1 angstroms =0.1 nm) is formed immediately on the surface of aluminum, so that aluminum will not be further oxidized and can withstand water.

Aluminum powder, when mixed with air, burns easily; Molten aluminum can react violently with water; At high temperature, many metal oxides can be reduced to corresponding metals; Aluminum is amphoteric, soluble either in strong bases or in dilute acids.
