2 Fe2O3 (s) + 3 C (s) → 4 Fe (s) + 3 CO2 (g)
This is an oxidation-reduction (redox) reaction:
3 C0 - 12 e- → 3 CIV (oxidation)
4 FeIII + 12 e- → 4 Fe0 (reduction)
C 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.]
