8 Al (s) + 15 H2SO4 (aq) → 4 Al2(SO4)3 (aq) + 3 H2S (g) + 12 H2O (l)
This is an oxidation-reduction (redox) reaction:
3 SVI + 24 e- → 3 S-II (reduction)
8 Al0 - 24 e- → 8 AlIII (oxidation)
H2SO4 is an oxidizing agent, Al is a reducing agent.
Reactants:
Products:
- Al2(SO4)3 – Aluminium sulfate
- H2S – Hydrogen sulfide

- Appearance: Colorless gas ; Colourless compressed liquefied gas with characteristic odour of rotten eggs ; Colorless gas with a strong odor of rotten eggs. [Note: Sense of smell becomes rapidly fatigued & can NOT be relied upon to warn of the continuous presence of H2S. Shipped as a liquefied compressed gas.]
- H2O – Water, oxidane
