Answer:
(i) Anode reaction: At the anode during the electrolysis of aqueous CuSO4 using a copper electrode, the reaction is: Cu(s) → Cu2+(aq) + 2e-
(ii) Observation at the anode: The copper electrode gradually dissolves.
(iii) Cathode reaction: At the cathode, the reaction is: Cu2+(aq) + 2e- → Cu(s)
(iv) Observation at the cathode: Copper metal is deposited on the cathode.
(i) The reaction at the anode during the electrolysis of aqueous CuSO4 using a copper electrode is: Cu(s) -> Cu2+(aq) + 2e-
(ii) The observation at the anode is that the copper electrode gradually dissolves and loses mass.
(iii) The reaction at the cathode during the electrolysis of aqueous CuSO4 using a copper electrode is: Cu2+(aq) + 2e- -> Cu(s)
(iv) The observation at the cathode is that a layer of copper metal deposits on the electrode.
