Principle
Carbon dioxide reacts with calcium hydroxide to form a white precipitate of calcium carbonate. Mineral water frequently contains natural or added carbon dioxide. Carbon dioxide forms a weak acid with water, carbonic acid. Carbon dioxide is therefore designated as the anhydride of carbonic acid.
