Jun 15, 2008· Answer. Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't 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.

THE LIME CYCLE. The lime cycle consists of first burning of limestone to form quicklime. Hydrated lime can then be produced by adding water to the quicklime. At this point, carbon dioxide in the atmosphere or from industrial processes react with hydrated lime to convert it back to limestone. This cycle is called the lime cycle.
