Limestone and Acid Rain
2011-11-21 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. Because surface waters are in equilibrium with atmospheric carbon dioxide there is a constant concentration of carbonic acid, H 2 CO 3, in the water.

What Does Acid Rain Do to Limestone? eHow
Surficial Limestone Effects. As acid rain falls to the earth's surface, limestone rocks and limestone components in soil will react with the rain, neutralize the acid and dissolve. As the limestone dissolves, the rocks will wear away, becoming pitted with rounded edges. The dissolution process will change the appearance of the landscape as the

How Often to Change a Condensate Neutralizer:
The primary compound in limestone is calcium carbonate. When the calcium carbonate reacts with acidic condensate, it forms carbon dioxide, water, and insoluble salts. These salts coat the resulting limestone, impairing the further neutralizing effect of the media. As a result, limestone media is quickly rendered ineffective and must be replaced.
