Question

If you are given some copper sulphate crystals, how would you proceed to prepare its saturated solution at room temperature?

Answer 1

1. Fill the beaker with distilled water.

2. Heat the beaker of water at ${100}^{0}C$, the solubility of copper(II) sulfate is 736 grams per kg of water.

3. Stop heating the water near ${100}^{0}C$.

4. Add copper sulfate and stir until the heated solution is saturated and at saturation no more copper sulfate will dissolve.

5. Cooled solution is supersaturated solution.
