The Effects of Acid Rain
Chalk, composed of limestone, represents statues in this activity. Limestone contains calcium carbonate (CaCO 3), which reacts chemically with acids, causing it to deteriorate or erode. The acid causes the calcium (Ca) and carbonate (CO 3) in the limestone to separate into calcium and carbon dioxide gas (CO 2).
