✔ 最佳答案
Nitric acid (HNO3)
NO2 + OH· → HNO3
Sulphuric acid (H2SO4)
SO2 + OH· → HOSO2
HOSO2· + O2 → HO2· + SO3
SO3(g) + H2O(l) → H2SO4(l)
Unpolluted rain has a slightly acidic pH of about 5.5, because carbon dioxide and water in the air react together to form carbonic acid (H2CO3)
H2O (l) + CO2 (g) → H2CO3 (aq)
