2 KMnO4 (aq) + 10 KBr (aq) + 16 HCl (aq) → 5 Br2 (aq) + 2 MnCl2 (aq) + 12 KCl (aq) + 8 H2O (l)
This is an oxidation-reduction (redox) reaction:
10 Br-I - 10 e- → 10 Br0 (oxidation)
2 MnVII + 10 e- → 2 MnII (reduction)
KBr is a reducing agent, KMnO4 is an oxidizing agent.
Reactants:
- KMnO4 – Potassium manganate(VII)
- KBr
- 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.]
