27. Solving a chemistry problem

2. What reactions occur on the electrodes during the electrolysis of a zinc sulfate solution:
a) with graphite anode;
b) with a zinc anode. How will the concentration of zinc ions in the solution change in both cases if a current of 26.8 A is passed through the solution for 1 hour? The current efficiency at the zinc cathode is 50%, at the anode – 100%.
