3 SO2 (g) + 4 NH3 (g) → 2 N2 (g) + 3 S (s) + 6 H2O (l)
This is an acid-base reaction (neutralization): SO2 is an acid, NH3 is a base.
This is an oxidation-reduction (redox) reaction:
3 SIV + 12 e- → 3 S0 (reduction)
4 N-III - 12 e- → 4 N0 (oxidation)
SO2 is an oxidizing agent, NH3 is a reducing agent.
