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...

In a galvanic cell, a spontaneous redox reaction occurs. However, the reactants are separated such that the transfer of electrons is forced to occur across a wire. The resulting electricity is measured in volts (V) and is the sum of the potentials of the oxidation and reduction half-reactions: E^o_cell = E^o_rad + E^o_ox By reversing the reduction half-reactions, you get the corresponding oxidation half-reaction, for which E^o_ox has the opposite sign of E^o_rod. You can also write the equivalent equation...
