Step 1 produces a carbonic acid from the acid added to the solution and reacting with the calcium carbonate in the limestone. The resulting reaction is as follows: CaCO 3 (s) + 2HCl (aq) → CaCl 2 (aq) + CO 2 (g) + H 2 O (l) (French et al., 77). The carbonic acid produced in step 1 decomposes in step 2 to form a carbon dioxide gas as shown:

How does weathering affect limestone? - Internet Geography

Aug 31, 2021 · Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.
