Question

Team JKSSB Mock Tests · Accepted Answer

Marble is primarily calcium carbonate (CaCO₃). It reacts with acid rain (containing H₂SO₄ and HNO₃) to form soluble salts, causing erosion: CaCO₃ + H₂SO₄ → CaSO₄ + H₂O + CO₂. This is why monuments like Taj Mahal are affected. CaCO₃ is basic, so it neutralizes acid. Restoration and pollution control are needed to protect heritage.
