5 KI (aq) + 6 KMnO4 (aq) + 18 HCl (aq) → 5 KIO3 (aq) + 6 MnCl2 (aq) + 6 KCl (aq) + 9 H2O (l)
This is an oxidation-reduction (redox) reaction:
6 MnVII + 30 e- → 6 MnII (reduction)
5 I-I - 30 e- → 5 IV (oxidation)
KMnO4 is an oxidizing agent, KI is a reducing agent.
Reactants:
- KI
- 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.]
