Verified answer
Answer:
(i) At the anode during the electrolysis of aqueous CuSO4 using inert electrodes, the reaction is: 2H2O(l) → O2(g) + 4H+(aq) + 4e-
(ii) The observation at the anode is the formation of oxygen gas bubbles.
(iii) At the cathode, the reaction is: Cu2+(aq) + 2e- → Cu(s)
(iv) The observation at the cathode is the deposition of copper metal.
