Calcium carbonate | CaCO3 - PubChem

Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement forCalcium carbonate - Wikipedia,Chemistry. Calcium carbonate shares the typical properties of other carbonates. Notably it reacts with acids, releasing carbon dioxide (technically speaking, carbonic acid, but that disintegrates quickly to CO 2 and H 2 O):; CaCO 3 (s) + 2 H + (aq) → Ca 2+ (aq) + CO 2 (g) + H 2 O(l). releases carbon dioxide upon heating, called a thermal decomposition reaction, or calcination (to above 840,Thermal decomposition of calcium carbonate | Experiment,,Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide.
