Jun 15, 2008 Limestone is mostly made up of the mineral calcium carbonate CaCO3. This is not very soluble, so rocks dont dissolve very quickly. But if you add an acid, you add hydrogen ions H, which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen
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.
Calcium carbonate limestone is heated to form calcium oxide quicklime and carbon dioxide It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
An experiment conducted by Ken Simmons has proved that calcium carbonate helps neutralize the effects of harmful acid rains in a river water ecosystem. Ground calcium carbonate GCC acts as a reagent in flue-gas desulfurization applications by eliminating sulfur dioxide emissions from coal and other fossil fuels.
