Calcium carbonate is a chemical compound of formula CaCO3, in white powder form. Calcium carbonate is practically undissolved in water (only 1.4 mg per 100 ml of water). But if the water contains carbon dioxide, the dissolution of calcium carbonate in the water increases due to the formation of bicarbonate.Calcium carbonate is rapidly degraded due to the effect of acids on it, as it liberates carbon dioxide.
