With carbon (graphite) electrodes, the oxygen usually reacts with the anode to form CO 2 If copper is used for the electrodes, the copper anode dissolves The reaction is the reverse of the cathode reaction The results of this experiment can lead to a discussion about electroplating and the electrolytic refining of purification of ores such as copper sulfide ore Electrolysis uses an electrical current to move ions in an electrolyte solution between two electrodes In copper electrolysis, when a current is applied, positivelycharged copper ions (called cations) leave the anode (positive electrode) and move toward the cathode (negative electrode)The Chemistry of Copper Electrolysis Superfund Electrolysis of Copper Sulfate Whenever copper sulfate or CuSO 4 is added to water, it gets dissolved in the water As CuSO 4 is an electrolyte, it splits into Cu + + (cation) and SO 4 − − (anion) ions and move freely in the solution Now we will Principle of Electrolysis of Copper Sulfate Electrolyte
