How can DRY calcium carbonate be prepared from sodium carbonate?
Na2Co3 + CaCl2 --- NaCL + CaCo3. but how to get dry calcium carbonate
Put the product in a drying oven at 105 C and leave it for a couple of hours.
To prepare dry calcium carbonate (CaCO3) from sodium carbonate (Na2CO3), you can follow these steps:
1. Start with the reaction between sodium carbonate (Na2CO3) and calcium chloride (CaCl2) as shown in the equation: Na2CO3 + CaCl2 → 2NaCl + CaCO3.
2. Prepare a solution by dissolving sodium carbonate (Na2CO3) in water.
3. Similarly, dissolve calcium chloride (CaCl2) in water to form a separate solution.
4. Combine the two solutions together. As you mix them, a white precipitate of calcium carbonate (CaCO3) will start to form.
5. Once the reaction is complete, you will need to separate the calcium carbonate precipitate from the remaining liquid solution. This can be done through filtration.
6. Set up a filtration apparatus by placing a funnel over a filter paper or a fine mesh filter.
7. Slowly pour the mixture through the filter. The calcium carbonate particles will be trapped in the filter paper or on the filter.
8. After filtration, you will have a wet cake of calcium carbonate. At this stage, it is not dry yet.
9. To dry the calcium carbonate, you can use a lab oven or other drying equipment set at a low temperature. The drying process will remove the remaining water, leaving you with dry calcium carbonate.
10. Make sure to monitor the drying process to prevent overheating and ensure that the calcium carbonate remains stable.
By following these steps, you can prepare dry calcium carbonate from sodium carbonate.
