Question

Explain with chemical equations involved in the formation of acid rain.

Answer 1

CO2(g) + H2O(l) ⇌ H2CO3(aq) ⇌ H+(aq) + HCO3−(aq)

Answer 2

Dear Aayush,

● Acid rain -

• Rainfall with excess of hydrogen ions in it (pH < 7) is called acid rain.
• Sulphur dioxide (SO2) & nitrogen oxide (NO2) in air on coming in contact with rain turns into sulphuric acid & nitric acid respectively.

2 SO2 + O2 + 2 H2O --> 2 H2SO4

4 NO2 + O2 + 2 H2O --> 4 HNO3

Thanks dear. Hope that was helpful...
