What material does acid rain have?

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)

in acid rain
the pollutant of SO2 CO2 and NO can dissolve in aqueous solvent
SO2+H2O----->H2SO3 (sulphurous acid)
CO2+H2O----->H2CO3 (carbonic acid)
NO+H2O------>HNO2+HNO3 (nitrous acid and nitric acid)
and some ashes, hydrocarbons
