However, solubility increases dramatically with increasing water acidity, which is accomplished by adding acids, either inorganic or organic, or by adding acid-forming gasses such as carbon dioxide and the oxides of sulfur and nitrogen to water.

NettetWhen carbonic acid flows through the cracks of some rocks, it chemically reacts with the rock causing some of it to dissolve. Carbonic acid is especially reactive with calcite, which is the main mineral that makes up limestone. Over many thousands of years, the dissolving action of carbonic acid on limestone sometimes produces underground caves. NettetGround dissolution occurs when water passing through soluble rocks produces underground cavities and cave systems. These cavities reduce support to the ground above and can cause localised collapse of the overlying rocks and deposits.
