| Reactions of Aluminium |
 Reactions with water |
| A thin layer of oxide prevents aluminium being attack by water. |
| Reactions with air |
| A thin layer of oxide prevents aluminium being attack by air. Aluminium will burn in oxygen with a brillian white flame to form aluminium trixode.

4Al + 3O2(g) 2Al2O3(s) |
| Reactions with halogens |
| Aluminium reacts vigorously with all halogens to form aluminium halides. |
| 2Al(s) + 3Cl2(g)2AlCl3(s) |
| 2Al(s) + 3Br2(l)AlBr26(s) |
| 2Al(s) + 3I2(l)Al2I6(s) |
| Reactions with acids |
| Aluminium dissolves readily in dilute suphuric acid for form solutions containing the Al(III) ion and hydroden gas.
|
| 2Al(s) + 3H2SO4(aq)2Al3+(aq) + 2SO42-(aq) + 3H2(g) |
| The reaction with dilute hydrochloric acid also yield the same Al(III) ion and hydrogen gas.
|
| 2Al(s) + 6HCl(aq)2Al3+(aq) + 6Cl-(aq) + 3H2(g) |
| Reactions with bases |
| Aluminium dissolves in sodium hydroxide to yield hydrogen gas and aluminates of the form [Al(OH)4]-.
|
| 2Al(s) + 2NaOH(aq) + 6H2O(l)2Na+(aq) + 2[Al(OH)4]- + 3H2(g) |
