ELECTROLYSIS OF COPPER CHLORIDE INTRODUCTION This investigation is aimed to monitor the quantity of Copper (Cu) metal deposited during the electrolysis of copper chloride solution (CuSo4) using Carbon electrodes, when only a specific variable is changed. The passing of a constant electric current through an aqueous copper chloride solution indicates that the passage of ions through this solution results in the chloride ions moving to the anode while positive copper ions (cations) being discharged at the cathode. This statement is empowered by the ionic theory of electrolysis, which states that the cations are attracted to the cathode and anions towards the anode. At the anode (+): Cl? ions lose an electron to the positive anode and form a neutral chlorine atom. Cl? Cl + e? The chlorine atoms then join up in pairs to form molecules of chlorine gas, Cl2. These molecules of chlorine gas now bubble off at the anode. Cl + Cl =...
