Why are SO₂ and NOₓ important in the chemistry of precipitation?
Answer and explanation
Correct answer: Because they can react in the atmosphere and contribute to acid rain
The governing concept is acid deposition. SO₂ can be oxidised to sulphur oxides and ultimately form sulphuric acid, while NOₓ can produce nitric acid through atmospheric reactions involving oxidants and water. These acids dissolve in cloud droplets and lower the pH of precipitation. Option B is correct; the other statements are chemically or physically unrealistic.
