KMnO2 + FeCl2 + 4 HCl → MnCl2 + FeCl3 + KCl + 2 H2O
This is an oxidation-reduction (redox) reaction:
MnIII + e- → MnII (reduction)
FeII - 1 e- → FeIII (oxidation)
KMnO2 is an oxidizing agent, FeCl2 is a reducing agent.
Reactants:
- KMnO2
- FeCl2 – Iron(II) chloride , Iron dichloride
- 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.]
