Calcium Carbonate (CaCO3) Uses, Preparation,

Calcium carbonate is an inorganic chemical compound with the chemical formula CaCO 3. Calcium carbonate is one of the most popular chemicals which is first encountered in school classrooms, where the use of chalk (a form of CaCO3) is found. It is found in the earth’s crust. It is also found in many forms such as marble, limestone, etc.

During the 1700s, limestone was used for lithography which is when pictures are drawn on stones and then copied to other stones. Because limestone contains the remains of dead organisms, it is considered an organic sedimentary rock. There are rare chemical sedimentary rocks that form from the precipitation of calcium carbonate from ocean water.
