Explain briefly how pure dry crystals of calcium chloride could be obtained from a solution of calcium chloride.
Heat the solution to concentrate it then leave it in a warm place then partially evaporate solution and allow to cool filter off crystals , pick out crystals. Dry crystals with filter paper
Heat the solution to concentrate it, then leave it in a warm place, then partially evaporate the solution and allow to cool filter off crystals. Pick out the crystals, then dry the crystals with filter paper.
Heat the solution to concentrate it leave it on a warm place the partially evaporate solution and allow to cool filter off crystals, pick out crystals,dry crystals with filter paper
Nothing
to add to what Presh said,
lol.
Heat the solution to concentrate it/ leave in a warm place / partially evaporate solution and allow to coolfilter off crystals / pick out crystals dry crystals with filter paper
Yes, that is correct. To summarize:
1. Heat the solution to concentrate it.
2. Allow the concentrated solution to cool to form crystals.
3. Filter the crystals from the solution.
4. Wash the crystals with a small amount of cold water to remove any impurities.
5. Dry the crystals between filter paper to remove any excess water.

To obtain pure dry crystals of calcium chloride from a solution, you can use the process of evaporation. Here's a brief explanation of the steps involved:
1. Start with a solution of calcium chloride: Begin with a solution containing calcium chloride dissolved in water. This solution could be obtained from a variety of sources, such as a chemical supplier or by dissolving solid calcium chloride in water.
2. Remove excess water: The next step involves removing the excess water from the solution. This can be done through evaporation. One way to do this is by placing the solution in a heat-resistant container, such as a glass beaker or evaporating dish.
3. Apply heat: Apply heat to the container containing the solution. This can be accomplished by using a Bunsen burner, hot plate, or other heating devices, depending on the available equipment.
4. Evaporate the water: Heat the solution gently to accelerate the evaporation process. As heat is applied, the water molecules will start to evaporate, leaving behind the dissolved calcium chloride crystals. It is important to continue heating until all the water has completely evaporated.
5. Observe crystal formation: As the water evaporates, the calcium chloride crystals will start to precipitate out of the solution. These crystals may form on the sides or bottom of the container, depending on the conditions and the presence of any impurities.
6. Collect the crystals: Once the solution has completely evaporated, you can collect the calcium chloride crystals. These crystals can be carefully scraped or poured out from the container using a spatula or other suitable tool.
7. Dry the crystals: Finally, to ensure that the crystals are completely dry and free from any remaining moisture, they should be left to air-dry for some time or placed in a desiccator to remove any traces of water.
By following these steps, you should be able to obtain pure dry crystals of calcium chloride from a solution.
