Calcium carbonate has a very low solubility in pure water (15 mg/L at 25°C), but in rainwater saturated with carbon dioxide, its solubility increases due to the formation of more soluble calcium bicarbonate. Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases.

Calcium carbonate will decompose to form carbon dioxide and calcium oxide. Carbonate compounds will decompose when heated. Here is the balanced equation for this reaction: CaCO_3(s) -> CaO(s) + CO_2(g) Calcium carbonate has a 1:1 ratio because calcium forms a +2 ion and carbonate has a -2 charge. Calcium oxide must have the formula CaO because calcium forms an ion with a +2 …

Calcium carbonate is a chemical compound with the formula Ca CO 3. It is a common substance found in rocks as the mineral s calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of eggshell s, snail shells, seashell s …

Calcium Carbonate Supersaturation Su-persaturated solutions of calcium carbonate can be formed from saturated or undersaturated solutions when the calcium hardness, pH or alkalinity are increased. The degree of calcium carbonate saturation (S) is given by the ratio of the actual ion activity product (IAP) and the thermodynamic solubility prod-
