To prepare calcium nitrate from CaCO3, you can follow these steps:
1. Start by heating CaCO3 (calcium carbonate) in a crucible or a heat-resistant container to decompose it into calcium oxide (CaO) and carbon dioxide (CO2). The reaction is as follows:
CaCO3 (s) → CaO (s) + CO2 (g)
2. Once the CaCO3 has decomposed, allow the calcium oxide (CaO) to cool down.
3. Next, dissolve the cooled calcium oxide (CaO) in dilute nitric acid (HNO3) to form calcium nitrate (Ca(NO3)2) and water (H2O). The reaction is as follows:
CaO (s) + 2HNO3 (aq) → Ca(NO3)2 (aq) + H2O (l)
4. Filter the solution to remove any undissolved solid particles.
5. Finally, evaporate the filtered solution to concentrate the calcium nitrate solution. Allow the solution to cool down, and calcium nitrate crystals will form.
6. Collect the calcium nitrate crystals by filtration, wash them with cold water, and dry them to obtain solid calcium nitrate.
By following these steps, you can prepare calcium nitrate from CaCO3.
