What happens when acid reacts with limestone? | Science …
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. Or, if there is …

limestone, quicklime and slaked lime
Although we almost always write the equation for this reaction as one-way, it is in fact reversible. CaCO 3 (s) CaO(s) + CO 2 (g) When you heat limestone in the open air, of course, the carbon dioxide just gets lost and the back reaction can't happen. In an enclosed kiln, though, it can. The net effect of this is to stop the limestone decomposing.

Q: How does limestone contribute to the carbon cycle?
Carbon dioxide (CO2) combines with water as raindrops fall through the atmosphere. This makes a weak acid, called carbonic acid. Carbonic acid is a very common in nature, where it works to dissolve rock, particularly limestone. In areas where carbonic acid seeps into limestone rock layers, the rock can be dissolved over time to create caves.
