Chemical Properties. From a chemical standpoint, Calcium Carbonate is a base that reacts with acids to form calcium salts, water, and carbon dioxide. Its solubility in water is quite low, but it dissolves in acid, producing a solution of calcium ions, water, and carbon dioxide gas. CaCO 3 + 2HCl → CaCl 2 + H 2 O + CO 2.
