2 NO (g) + SO2 (aq) + H2O (l) → H2SO4 (aq) + N2O (g)
This is an oxidation-reduction (redox) reaction:
SIV - 2 e- → SVI (oxidation)
2 NII + 2 e- → 2 NI (reduction)
SO2 is a reducing agent, NO is an oxidizing agent.
Reactants:
- NO – Nitrogen monoxide , Oxidonitrogen(•) (additive)
- 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.]
