2 MnO + 4 HCl → 2 MnCl + Cl2 + 2 H2O
This is an oxidation-reduction (redox) reaction:
2 MnII + 2 e- → 2 MnI (reduction)
2 Cl-I - 2 e- → 2 Cl0 (oxidation)
MnO is an oxidizing agent, HCl is a reducing agent.
Reactants:
- MnO – Manganese(II) oxide
- 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.]
