Fe + 4 KMnO4 + 4 HCl → Fe(MnO4)3 + MnO2 + 4 KCl + 2 H2O
This is an oxidation-reduction (redox) reaction:
MnVII + 3 e- → MnIV (reduction)
Fe0 - 3 e- → FeIII (oxidation)
KMnO4 is an oxidizing agent, Fe is a reducing agent.
Reactants:
- Fe
- KMnO4 – Potassium manganate(VII)
- 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.]
