![]() However, if carbon dioxide becomes excess, it produces a soluble calcium hydrogen carbonate. ![]() For preparation on a large scale, the process is bypassing the carbon dioxide gas through calcium hydroxide (slaked lime).When the carbon dioxide pass in bulk, it contributes to the production of calcium hydrogen carbonate. Another approach used to produce calcite is the addition of sodium carbonate to calcium chloride. When carbon dioxide passes through the slaked lime, it obtains the calcite. CaCO 3 is produced by the use of carbon dioxide and slaked lime as raw materials. ![]() Preparation of Calcium Carbonate (CaCO 3) It is widely applicable in the manufacturing industry as a building material (marble), a quick-lime and a cement ingredient.And as a disinfectant agent in swimming pools and as a pH corrector. Also, it is useful medicinally as an antacid or a calcium supplement, also sometimes used as a filler in cosmetics.It is a white insoluble powder-like material that occurs naturally in calcites, minerals, limestone, chalk, marble, shells, pearls, and etc.It is an inorganic chemical substance with a chemical formula of CaCO 3.Calcium carbonate is a known non-toxic and odourless compound widely found as a white mineral that naturally occurs in limestones, chalks, marbles and pearls. ![]() Though they are available in different forms, they are chemically identical and differ only physically. It can also be present in many other kinds, such as marbles, limestone, etc. It is also present in the crust of the earth. Calcium carbonate is a chemical compound which, is among the most common chemical compounds first encountered in school classrooms where the chalk usage (a form of CaCO 3) is common. 2 FAQs about Calcium Carbonate What is Calcium Carbonate?Ĭalcium carbonate is the inorganic chemical substance with a chemical formula CaCO 3. ![]()
