How to get calcium carbonate in three ways and how to isolate it from the mixture?
August 13, 2021 | education
| Calcium carbonate can be obtained in a variety of ways.
Methods of obtaining:
1. Interaction of soluble calcium salt and soluble carbonate:
CaCl2 + Na2CO3 = CaCO3 + 2 NaCl
2. Neutralization reaction (interaction of calcium hydroxide with carbonic acid):
Ca (OH) 2 + H2CO3 = CaCO3 + 2 H2O
3. Interaction of quicklime (calcium oxide) with carbon dioxide:
CaO + CO2 = CaCO3
To isolate calcium carbonate from a mixture, it is sufficient to prepare an aqueous solution and filter CaCO3, since this salt is insoluble in water.
