When all the crystals are dissolved, stop heating, remove from the beaker from the hotplate, and place it on a thermal pad or wire gauze. While stirring, carefully add the iron filings to the hot copper sulfate solution.When all the iron has been added, let the solution react for ten more minutes.ince the number of moles of iron that reacts will be equal to the number of moles of copper produced, the number of copper atoms produced should be the same as the number or iron atoms we start with. You will first make a copper sulfate solution by dissolving copper sulfate crystals in hot water.
