4 FeCl2 + KMnO4 + 8 HCl → KCl2 + MnCl2 + 4 FeCl3 + 4 H2O
This is an oxidation-reduction (redox) reaction:
MnVII + 5 e- → MnII (reduction)
KI - 1 e- → KII (oxidation)
4 FeII - 4 e- → 4 FeIII (oxidation)
KMnO4 is an oxidizing agent, KMnO4 is a reducing agent, FeCl2 is a reducing agent.
Reactants:
- FeCl2 – Iron(II) chloride , Iron dichloride
- 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.]
