2 VO + 3 Fe2O3 → V2O5 + 6 FeO
This is an oxidation-reduction (redox) reaction:
2 VII - 6 e- → 2 VV (oxidation)
6 FeIII + 6 e- → 6 FeII (reduction)
VO is a reducing agent, Fe2O3 is an oxidizing agent.
Reactants:
- VO – Vanadium(II) oxide
- 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.]
