Question

Discuss in brief toxic
effect of so2 and so3​

Answer 1

Answer:

2 H2S + 3 O2 → 2 H2O + 2 SO2The roasting of sulfide ores such aspyrite, sphalerite, and cinnabar (mercury sulfide) also releases

SO2:[15]4 FeS2 + 11 O2 → 2 Fe2O3 + 8 SO22 ZnS + 3 O2 → 2 ZnO + 2 SO2HgS + O2 → Hg + SO24 FeS + 7O2 → 2 Fe2O3 + 4 SO2A

combination of these reactions is responsible for the largest source of sulfur dioxide, volcanic eruptions. These events can release millions of tonnes of SO2.
