Get your answers by asking now. Dry it off on a paper towel. Electricity is passed through solutions containing copper compounds, such as copper(II) sulfate. The anode (positive electrode) is made from impure copper and the cathode (negative electrode) is made from pure copper. All other trademarks and copyrights are the property of their respective owners. This essentially forces the electricity down the piece of copper, or conducts it down the metal. The copper will not bond where the marker is. The pure copper rod is connected to the negative terminal of a battery, and the impure rod is connected to the positive terminal, 3. Explanation: Copper sulphate is an ionic compound which means the compound will dissociate into ions so it will start conducting electricity. - Definition & Formula, What is Static Electricity?
