| Video Discription | Aluminium by itself is a very reactive metal. However, aluminium is oxidized when exposed to air, forming a thin layer of protective aluminium oxide on its surface. When some aluminium foil is added to a solution of copper(II) chloride in concentrated hydrochloric acid, the layer of aluminium oxide will be destroyed by chloride ions. Al2O3 + 2Cl- + 3H2O → 2[Al(OH)2Cl] + 2OH- The exposed aluminium metal reacts with hydrochloric acid, producing hydrogen gas. 2Al + 6H3O+ → 2Al3+ + 6H2O + 3H2 Hydrogen gas can be ignited. The color of the flame is blue/green due to the presence of Cu2+ ions. Hazards: - Hydrochloric acid is very corrosive |
