3 Na2MoO4 + 4 Al + 24 HCl → 3 MoCl2 + 4 AlCl3 + 6 NaCl + 12 H2O
This is an oxidation-reduction (redox) reaction:
3 MoVI + 12 e- → 3 MoII (reduction)
4 Al0 - 12 e- → 4 AlIII (oxidation)
Na2MoO4 is an oxidizing agent, Al is a reducing agent.
Reactants:
- Na2MoO4 – Sodium molybdate
- Al
- HCl – Chlorane , Hydrogen chloride
- Other names: Hydrochloric acid , M , Uriatic acid
- Appearance: Colorless, transparent liquid, fumes in air if concentrated ; Colorless gas ; Colourless compressed liquefied gas with pungent odour ; Colorless to slightly yellow gas with a pungent, irritating odor. [Note: Shipped as a liquefied compressed gas.]
