2 Al (s) + Fe2O3 (s) → 2 Fe (s) + Al2O3 (s)
This is an oxidation-reduction (redox) reaction:
2 Al0 - 6 e- → 2 AlIII (oxidation)
2 FeIII + 6 e- → 2 Fe0 (reduction)
Al is a reducing agent, Fe2O3 is an oxidizing agent.
- Fe2O3 – Iron(III) oxide
- Other names: Ferric oxide , Hematite , Ferric iron
- Appearance: Red-brown solid ; Reddish brown-to-black crystals or powder ; Reddish-brown solid. [Note: Exposure to fume may occur during the arc-welding of iron.] ; A fine, red powder of ferric oxide. [Note: Usually used in cake form or impregnated in paper or cloth.]
