Calcium Carbonate (CaCO3) Uses, Preparation,
Preparation of CaCO3. 1. 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. Ca (OH)2 + CO2 → CaCO3 + H2O.
