8 Al (s) + 3 KNO3 (aq) + 30 HCl (aq) → 3 NH4Cl (aq) + 8 AlCl3 (aq) + 3 KCl (aq) + 9 H2O (l)
This is an oxidation-reduction (redox) reaction:
8 Al0 - 24 e- → 8 AlIII (oxidation)
3 NV + 24 e- → 3 N-III (reduction)
Al is a reducing agent, KNO3 is an oxidizing agent.
Reactants:
- Al
- KNO3 – Potassium nitrate
- 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.]
