I2 + 7 MnO2 + 14 HCl → 2 HIO4 + 7 MnCl2 + 6 H2O
This is an oxidation-reduction (redox) reaction:
7 MnIV + 14 e- → 7 MnII (reduction)
2 I0 - 14 e- → 2 IVII (oxidation)
MnO2 is an oxidizing agent, I2 is a reducing agent.
Reactants:
- I2
- MnO2 – Manganese oxide , Manganese(IV) 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.]
