Pour the copper sulfate into an Erlenmeyer flask containing 6.3 fluid oz of warm water and wait for the copper sulfate to dissolve completely.
Add the baking soda to the solution slowly. If the solution begins to rise to the top of the flask, try adding the baking soda in small quantities and allow the solution to settle after each addition. Continue adding until you have used all of the baking soda. Leave the solution to stand. This will create copper carbonate.
Place a piece of filter paper into the bell of the funnel, and place the funnel into the second Erlenmeyer flask. Once the solution has finished reacting the copper carbonate will have settled to the bottom of the flask, with the water resting on top. Place a stopper into the top of the flask and swirl the flask to mix the solution with the water. Once the copper carbonate and water are mixed up, pour the solution on to the filter paper and through the funnel.
Scrape the copper carbonate off of the filter paper and into a dish once you have filtered the whole flask of solution. Allow the crystals to dry for 3 hours.
Pour the copper carbonate and 0.35 oz of carbon into a saucepan and place over a high heat for 15 to 20 minutes. This will initiate the reaction between the copper carbonate and carbon which will produce carbon dioxide gas and the copper metal.
Transfer the copper metal from the saucepan into a dish once the reaction has taken place and the mixture has darkened.
