A student plans a method to prepare pure crystals of copper sulfate. The student's method is:1.Add one spatula of calcium carbonate to dilute hydrochloric acid in a beaker.2.When the fizzing stops, heat the solution with a Bunsen burner until all the liquid is gone. The method contains several errors and does not produce copper sulfate crystals. Explain the improvements the student should make to the method so that pure crystals of copper sulfate are produced.
