What Are The Uses Of Aluminium?
How Does It Anodise?
Thermite Reaction
iron(III) oxide(s) + aluminium → aluminium oxide + iron
Test for Aluminium ions
Solutions containing aluminium ions are typically colourless in colour.
To test for the presence of aluminium ions in solution, you may use either the sodium hydroxide test or the ammonia test.
- Sodium Hydroxide Test - To a sample of your solution, add a few drops of sodium hydroxide solution. A white precipitate forms. Upon addition of excess sodium hydroxide, the white precipitate dissolves.
- Ammonia Test - To a sample of your solution, add a few drops of ammonia solution. A white precipitate forms. Upon addition of excess ammonia solution, the white precipitate remains insoluble.
Testing cations
Ammonium, Copper II, Iron II, Iron III, Zinc
