Calcium carbonate | CaCO3 - PubChem
Calcium carbonate | CaCO3 - PubChem

Precipitatedcalcium carbonate(CAS: 471-34-1) is produced industrially by the decomposition of limestone tocalcium oxidefollowed by subsequent recarbonization or as a by-product of the Solvayprocess(which is used to makesodium carbonate). Precipitatedcalcium carbonateis purer than groundcalcium carbonateand has different (and tailorable) handlingproperties.

What Is Lime Used for in Water Treatment? | Sciencing

Quicklime is made by heating calcium carbonate in a process called "calcining" to release carbon dioxide, leavingcalcium oxide. Quicklime can be further processed by crushing and adding a small amount of water, to make hydrated lime, also called slaked lime, which iscalcium hydroxide.

The precipitate is likely to be a mixture ofcalciumand magnesiumcarbonate, so the wholeprocesshas resulted in a decline in these ions. The decline is reasonably small (I’d estimate it to be about 0.5 meq/L based on the relationship between pH and alkalinity described previously), and involves a lot more solid per unit volume than would ...
