Understanding the Properties
* Copper sulfate: Soluble in water, forms blue solution.
* Calcium carbonate: Insoluble in water, white solid.
Separation Method
1. Dissolution: Add water to the mixture of copper sulfate and calcium carbonate. The copper sulfate will dissolve, forming a blue solution, while the calcium carbonate will remain as a solid.
2. Filtration: Filter the mixture through a filter paper. The calcium carbonate will be trapped on the filter paper, while the copper sulfate solution will pass through.
3. Evaporation: Carefully evaporate the water from the copper sulfate solution. This will leave behind solid copper sulfate crystals.
Here's a step-by-step breakdown:
1. Mix: Combine your mixture of copper sulfate and calcium carbonate in a suitable container.
2. Add Water: Add enough water to the mixture to dissolve all the copper sulfate. Stir thoroughly.
3. Filter: Use a funnel and filter paper to separate the solid calcium carbonate from the copper sulfate solution. The calcium carbonate will be left on the filter paper.
4. Evaporation: Gently heat the copper sulfate solution (use a hot plate or Bunsen burner with caution) to evaporate the water. As the water evaporates, copper sulfate crystals will form in the container.
5. Collection: Once the water has completely evaporated, you'll be left with solid copper sulfate crystals.
Important Notes:
* Safety: Always wear appropriate safety goggles and gloves when working with chemicals.
* Careful Heating: When evaporating the water, use a low heat to prevent splattering and ensure that the copper sulfate doesn't decompose.
