⭕ A. SO₂ and NO
⭕ B. NO and O₃
⭕ C. CO₂ and O₃
⭕ D. CO and CO₂
📚 Explanation:
Acid rain is mainly caused by air pollutants released from industrial processes, power plants, and vehicles.
🔹 The two major gases responsible are:
These gases react with moisture in the atmosphere to form:
✔ H₂SO₄ (Sulphuric acid)
✔ HNO₃ (Nitric acid)
Acid rain is mainly caused by air pollutants released from industrial processes, power plants, and vehicles.
🔹 The two major gases responsible are:
- SO₂ (Sulphur dioxide)
- NOₓ (Nitrogen oxides including NO)
These gases react with moisture in the atmosphere to form:
✔ H₂SO₄ (Sulphuric acid)
✔ HNO₃ (Nitric acid)
✔ These acids mix with rainwater → resulting in acid rain.
👉 Therefore, the correct answer is: A. SO₂ and NO
Key Points on Acid Rain:
- Primary pollutants: SO₂ and NOₓ.
- Formation: Converts to H₂SO₄ and HNO₃ in atmosphere.
- Effects: Damages soil, water bodies, vegetation, and buildings.
- Sources: Power plants, industries, vehicles.
