Cave / Karst Systems Carlsbad Caverns National Park (U.S

When the two waters mixed, the H 2 S combined with the oxygen carried by the rainwater and formed sulfuric acid (H 2 SO 4). This acid dissolved the limestone along fractures and folds in the rock to form Carlsbad Cavern. This process left behind massive gypsum deposits, clay, and silt as evidence of how the cave was formed.

Limestone and Acid Rain University Of Illinois

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.
