3 Cu + 4 HSO4 → 3 CuSO4 + SO2 + 2 H2O
This is an oxidation-reduction (redox) reaction:
3 Cu0 - 6 e- → 3 CuII (oxidation)
3 SVII + 3 e- → 3 SVI (reduction)
SVII + 3 e- → SIV (reduction)
Cu is a reducing agent, HSO4 is an oxidizing agent, HSO4 is an oxidizing agent.
Reactants:
- Cu
- HSO4
Products:
- CuSO4 – Copper(II) sulfate
- SO2 – Sulfur dioxide
- Other names: Sulfurous anhydride , Sulphur dioxide , Sulfurous acid anhydride
- Appearance: Colorless gas ; Colourless gas or compressed liquefied gas with pungent odour ; Colorless gas with a characteristic, irritating, pungent odor. [Note: A liquid below 14°F. Shipped as a liquefied compressed gas.]
