It is just like a battery, when fresh, one side is positive and one side is negative, and when consumed both sides are neutral, but the same amount of electrons and protons exist in both states. The pH of the solution is determined by the amount of H+ ions (H3O) but as hydrogen is reduced at the cathode it leaves the cell as H2 gas, but it leaves as a neutral species and so does not effect the net electrical state >>
Ivan: But if some OH- is generated at the cathode why doesn't the pH rise? If the reaction, (1) [H+] + [OH-} ------> H2O is consuming OH-, then where is the H+ coming from? If it's coming from the dissociation of water then the pH will rise since THAT reaction is the reverse of reaction (1).
