6 KIO3 (aq) + 10 Al (s) + 36 HCl (aq) → 10 AlCl3 (aq) + 3 I2 (s) + 6 KCl (aq) + 18 H2O (l)
This is an oxidation-reduction (redox) reaction:
6 IV + 30 e- → 6 I0 (reduction)
10 Al0 - 30 e- → 10 AlIII (oxidation)
KIO3 is an oxidizing agent, Al is a reducing agent.
Reactants:
- KIO3 – Potassium iodate
- Al
- 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.]
