Calcium carbonate Formula - Calcium carbonate Uses ...

Formula and structure: The chemical formula of calcium carbonate is CaCO 3 and its molar mass is 100.1 g/mol. It is a salt made of the bivalent calcium cation (Ca 2+) and the bidentate carbonate anion (CO 3 2-), in which the carbon is attached to two oxygen atoms through single bonds and one oxygen atom through a double bond.

The Many Faces of Calcium Carbonate

forms of the chemical compound calcium carbonate (CaCO 3). Calcium carbonate is often found in sea shells and bones of sea creatures, and when these settle on the ocean floor for millions of years it forms limestone. Limestone can also come from the combination of soluble calcium (Ca) and carbon dioxide (CO 2) from water in lakes and oceans.
