Calcium carbonate Wikipedia
Calcium carbonate shares the typical properties of other carbonatesNotably it reacts with acids, releasing carbonic acid which quickly disintegrates into carbon dioxide and water:; CaCO 3 (s) + 2 H + (aq) → Ca 2+ (aq) + CO 2 (g) + H 2 O(l) releases carbon dioxide upon heating, called a thermal decomposition reaction, or calcination (to above 840 °C in the case of CaCO 3), to
