Calcium Carbonate Preparation, Properties & Uses

On reacting with dilute acids, calcium carbonate gives carbon dioxide. CaCO 3 + H 2 SO 4 CaSO 4 + H 2 O +CO 2; Preparation of CaCO 3. CaCO 3 is obtained by using carbon dioxide and slaked lime as raw materials. When carbon dioxide is passed through slaked lime, calcite is obtained. Another method to obtain calcite is by adding sodium carbonate to calcium chloride.
