Limestone forms when calcite or aragonite precipitate out of water containing dissolved calcium, which can take place through both biological and nonbiological processes. The solubility of calcium carbonate (CaCO3) is controlled largely by the amount of dissolved carbon dioxide (CO2) in the water. This is summarized in the reaction:

Nettet11. jan. 2024 · The solubility of gypsum rock in 100 g water is greater than 200 mg at room temperature, while the solubility of limestone and dolomite is just 12 mg. Consequently, the dissolution of limestone and dolomite depends on CO 2 and acid strength ( equations (2) –( 7 )). 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. NettetAbstract. Samples of representative Illinois limestones and dolomites were ground in distilled water and the amount of water-soluble salts in the resulting leaches was determined by chemical analysis and by weighing the leach solids resulting from evaporating the leaches.
