The diagram shows the experimental setup for the electrolysis of aqueous copper(II) sulfate, CuSO4(aq)\text{CuSO}_4\text{(aq)}CuSO4(aq), using inert graphite electrodes.
Which products are discharged at the anode and the cathode during this electrolysis?
Anode: Oxygen (O2)\text{Oxygen (O}_2\text{)}Oxygen (O2), Cathode: Copper (Cu)\text{Copper (Cu)}Copper (Cu)
Anode: Copper (Cu)\text{Copper (Cu)}Copper (Cu), Cathode: Oxygen (O2)\text{Oxygen (O}_2\text{)}Oxygen (O2)
Anode: Oxygen (O2)\text{Oxygen (O}_2\text{)}Oxygen (O2), Cathode: Hydrogen (H2)\text{Hydrogen (H}_2\text{)}Hydrogen (H2)
Anode: Sulfur dioxide (SO2)\text{Sulfur dioxide (SO}_2\text{)}Sulfur dioxide (SO2), Cathode: Copper (Cu)\text{Copper (Cu)}Copper (Cu)
