Detailed explanation-1: -When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details.
Detailed explanation-2: -Reaction with acids Like all metal carbonates, calcium carbonate reacts with acidic solutions to produce carbon dioxide gas. It is this reaction that is responsible for limestone fizzing when dilute hydrochloric acid is placed on its surface.
Detailed explanation-3: -Calcium carbonate, [Ca][CO3] is a very common mineral. Limestone is one familiar form of calcium carbonate. Acids in acid rain promote the dissolution of calcium carbonate by reacting with the carbonate anion. This produces a solution of bicarbonate.
Detailed explanation-4: -Limestone contains calcium carbonate (CaCO3), which reacts chemically with acids, causing it to deteriorate or erode. The acid causes the calcium (Ca) and carbonate (CO3) in the limestone to separate into calcium and carbon dioxide gas (CO2).
