WebCalcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs. WebCa (OH)2 + CO2→ CaCO3 + H2O Properties of Calcium Carbonate – CaCO3 It is a fluffy powder. It decomposes to give carbon dioxide when heated up to 1200K. When it reacts with dilute acid, it liberates carbon dioxide as a by-product. CaCO3+H2SO4 → CaSO4+H2O+CO2 At 1200K, calcium carbonate decomposes to give carbon dioxide …
