Crystal structure of calcite. Calcium carbonate is a chemical compound with the chemical formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skeletons and pearls.Materials containing much calcium carbonate or resembling it are described as calcareous.
Calcium carbonate, chemically CaCO3, is a resonance-stabilized inorganic salt therapeutically used as a food additive, a dietary supplement, an antacid, and a phosphate binder. Calcium carbonate is among the most abundant compounds found in the earth's crust and is commonly found in organic substances, such as egg and oyster shells, crustaceans ...
Calcium carbonate (CaCO3), chemical compound consisting of one atom of calcium, one of carbon, and three of oxygen that is the major constituent of limestone, marble, chalk, eggshells, bivalve shells, and corals. Calcium carbonate is either a white powder or a colorless crystal. When heated, it
Learn about calcium carbonate (CaCO3), a common inorganic compound found in minerals, chalk, marble and limestone. Find out how it is prepared, its properties, applications and FAQs.
Structure of Calcium Carbonate. Calcium carbonate is characterized by its unique chemical structure, represented by the formula CaCO₃.At its core, this compound consists of one calcium (Ca) ion bonded to one carbonate (CO₃) ion. The carbonate ion is a polyatomic ion with a trigonal planar geometry, comprising one carbon atom centrally bonded to three oxygen atoms in a symmetrical arrangement.
Calcium carbonate (CaCO3) is a compound used as a dietary calcium supplement and as a common antacid. It is one of the most abundant compounds in the earth's crust and is found naturally in:

Calcium carbonate. Calcium carbonate is a chemical compound, with the chemical formula Ca C O 3.The elements involved are calcium (Ca), carbon (C) and oxygen (O). It is a common substance found as rock in all parts of the world, and is the main component of seashells, snails, and eggshell.. Calcium carbonate is usually the main cause of hard water.It is used as a calcium supplement or as a ...
CaCO3(s) → CaO(s) + CO 2 (g) Reaction with Water. Calcium Carbonate is insoluble in water under normal conditions but form calcium bicarbonate when react with carbon dioxide saturated water. CaCO 3 (s) + H 2 O(l) + CO 2 (g) → Ca(HCO 3) 2. Reaction with Acids. Calcium Carbonate when react with acid form calcium salt, water and carbon dioxide ...
Calcium carbonate is a chemical compound with the formula CaCO3 formed by three main elements: carbon, oxygen, and calcium. It is a common substance found in rocks in all parts of the world (most notably as limestone), and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells.
