    • What is the reaction of limestone with water?

      Limestone (CaCO 3) reacts with hydrogen ions in water. These are always present in water, since water undergoes autoprotolysis: H 2 O(l) = H + (aq) + OH-(aq) The more acidic the water is, the more limestone will react, and erode. The erosion of marble sculpture and inscriptions exposed to the elements is one of the consequences of acid rain.
