Fe2O3 (s) + H2 (g) → H2O (l) + 2 FeO (s)
This is an oxidation-reduction (redox) reaction:
2 H0 - 2 e- → 2 HI (oxidation)
2 FeIII + 2 e- → 2 FeII (reduction)
H2 is a reducing agent, Fe2O3 is an oxidizing agent.
Reactants:
- 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.]
