HINT: Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.
Explanation:
CO2 is slightly soluble in water forming carbonic acid.
CO2+H2O→H2CO3
The oxides of nitrogen undergo oxidation reaction followed by reaction with water vapour form nitric acid.
NO+O2→2NO2 2NO2+H2O→HNO3+HNO2
The oxidation of SO2 into SO3 in presence of dust particles or metal ions. SO3, then with water vapours to form H2SO4.
