What is the reduction half-reaction? In the electrolytic cell of this experiment, copper metal is the anode and zinc metal the cathode. The electrolyte solution is sulfuric acid, H2SO4. Oxidation occurs at the copper anode, where Cu is oxidized to Cu^2+: Cu (s) → Cu^2+ (aq) + 2 e– During the experiment, you might have noticed that at the end of the trials, the solution becomes slightly blue, which proves the existence of aqueous Cu^2+. What is the reduction half-reaction...
