Calcium Carbonate - an overview | ScienceDirect Topics

The solubility of calcium carbonate in water is very low, e.g., below 1 gram per litre at 20 °C under 1 atmosphere CO 2 pressure. Its solubility is strongly influenced by partial pressure of CO 2, temperature, and concentration of other salts in solution.Changes in super saturation and hence precipitation and scaling usually occur as a result of temperature increase or pressure decrease
