#### Calcium carbonate - Wikipedia

OverviewSolubilityChemistryPreparationStructureOccurrenceGeologyUses

Calcium carbonate is poorly soluble in pure water (47 mg/L at normal atmospheric CO2 partial pressure as shown below). The equilibrium of its solution is given by the equation (with dissolved calcium carbonate on the right): CaCO3 ⇌ Ca + CO 3 Ksp = 3.7×10 to 8.7×10 at 25 °C where the solubility productfor [Ca ][CO 3] is given as anywhere from Ksp = 3.7×10 to Ksp = 8.7×10 at

#### Calcium carbonate | CaCO3 - PubChem

Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for

#### Calcium Carbonate - an overview | ScienceDirect Topics

The calcium carbonate scaling usually occurs with a pressure drop, for example, at the wellbore. This reduces the partial pressure of CO 2, thereby increasing the pH and decreasing the CaCO 3 solubility. The solubility of calcium carbonate decreases with increasing temperature.

#### 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 ...
