Copper from a 200.0 mL solution of copper (II) sulfate is plated on to the cathode of an electrolytic cell. (a) Hydronium ions are generated at one of the electrodes. Is this electrode the anode or cathode? (b) How many moles of H3O+ are generated if a current of 0.120 A is applied to the cell for 30.0 h? (c) If the pH of the solution was initially 7.0, what will be the pH of the solution after the electrolysis? Assume no change in the volume of solution.
