Acid Rain MCQs

Acid rain is precipitation with a high level of acidity. While normal rain has a slightly acidic pH of around 5.6 due to the reaction of CO₂ with rainwater, acid rain has a pH that drops below 5.6, typically ranging from 4.2 to 4.4. This phenomenon primarily results from the presence of sulfur and nitrogen oxides in the atmosphere. These oxides react with water vapor to form acids. Power plants and large industries are major sources of these oxides. Acid rain has caused considerable damage to the Taj Mahal, leading to discoloration and structural damage.
