Balanced chemical equation of CaCO 3 and HCl reaction with physical states CaCO 3(s) + 2HCl (aq) → CaCl 2(aq) + CO 2(g) + H 2 O (l). Calcium carbonate is not soluble in water and exists as white precipitate in the water. When aqueous hydrochloric acid is added, you can observe air bubbles are generated and calcium chloride, carbon dioxide and water are formed.
