Answer:
CaCO3+2HCl→CaCl 2+H2 O+CO 2
Explanation:
Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3. Adding more carbon dioxide results in the precipitate dissolving to form a colourless solution of calcium hydrogencarbonate.
CaCO3+2HCl→CaCl 2+H2 O+CO 2
