Explain the formation of acid rain. How is it harmful
The solution is as follows:
1. Formation of acid rain:
-The combustion of sulphur and nitrogen containing compounds in industry leads to emission of SO2 and N2O2 in the atmosphere.
-These gases in the presence of O2 form SO3 and NO2.
-When it rains, these gases combine with water and form HNO3 and H2SO4 which are very strong acids. These acids come down with rain and acid rain is formed.
2. Harmful effects of Acid Rain:
-Dissolves nutrients essential for plant growth
