An excess of solid black copper(II) oxide is added to dilute sulfuric acid in a beaker to prepare a soluble salt.
copper(II) oxide (s)+sulfuric acid (aq)→copper(II) sulfate (aq)+water (l) \text{copper(II) oxide (s)} + \text{sulfuric acid (aq)} \rightarrow \text{copper(II) sulfate (aq)} + \text{water (l)} copper(II) oxide (s)+sulfuric acid (aq)→copper(II) sulfate (aq)+water (l)Describe the experimental procedure to obtain a sample of pure, dry copper(II) sulfate crystals from the mixture of copper(II) sulfate solution and excess solid copper(II) oxide in the beaker.
