Acid rain occur due to atmospheric pollution of: — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Acid rain is primarily caused by acidic gases that react with moisture in the atmosphere to produce sulfuric and nitric acids. Step 2: Among the listed options, sulfur dioxide (SO2) is a major contributor to acid rain as it is oxidized to sulfur trioxide and dissolves in water to form sulfuric acid (H2SO4). Step 3: Therefore, atmospheric pollution of SO2 is the correct answer, corresponding to option (a).
