These react to form carbon dioxide gas (CO 2), water (H 2 O), dissolved calcium (Ca ++), and dissolved chlorine (Cl--). The carbon dioxide bubbles that you observe are evidence that the reaction is taking place. When that occurs, calcite or another carbonate mineral is present. Many other carbonate minerals react with hydrochloric acid.
