Description A white powder that can occur in three crystalline forms: Calcite (hexagonalrhombohedral), Aragonite (orthorhombic) and vaterite. Calcium carbonate occurs naturally in many forms such as Chalk, Limestone, Marble and sea shells. It can be found worldwide and ranges in color (because of impurities) from white to gray to yellow.

· Calcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate. CaCO3 + CO2 + H2O → Ca (HCO3)2 What role does CO2 play in that reaction because, as you have just shown me, that reaction happens anyway in two steps without co2: 1) dissolution of ca/carbonate ions

calcium carbonate 1. n. [Drilling Fluids] A compound with formula CaCO 3 that occurs naturally as limestone. Ground and sized calcium carbonate is used to increase mud density to about 12 lbm/galUS [ kg/m 3 ], and is preferable to barite because it is acidsoluble and can be dissolved with hydrochloric acid to clean up production zones.
