For this problem, we have to determine the effect of increasing pH to the magnitude of cell potential

  • Recall that pH is the log of the concentration of H3O+ or H+ in the reaction. Higher pH, lower [H+]
  • Upon inspection, H3O+ is part of the cathode reaction:

4H3O+ (aq) + 4I- (aq) + O2 (g) → 2I2 (s) 6H2O (l).
