the procedure for calcium carbonate

Calcium Carbonate

The solubility of calcium carbonate in water is very low, eg, 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 solutionChanges in super saturation and hence precipitation and scaling usually occur as a result of temperature increase or pressure decrease ....
