Understanding the Properties
* Chalk (Calcium Carbonate): Insoluble in water, white powder.
* Copper Sulfate: Soluble in water, blue crystalline solid.
Separation Method
1. Dissolution: Add water to the mixture of chalk and copper sulfate. The copper sulfate will dissolve, forming a blue solution, while the chalk will remain undissolved as a solid.
2. Filtration: Use a filter paper and a funnel to separate the solid chalk from the copper sulfate solution. The chalk will be trapped on the filter paper, and the blue copper sulfate solution will pass through.
3. Evaporation: Gently heat the copper sulfate solution to evaporate the water. As the water evaporates, the blue copper sulfate crystals will begin to form. Once the water is completely evaporated, you will be left with pure copper sulfate crystals.
Important Considerations:
* Safety: Wear appropriate safety goggles and gloves, as copper sulfate is an irritant.
* Heat: Be careful when heating the copper sulfate solution. The solution should be heated gently to prevent splattering.
