Answer #1

f this is the reaction at the anode: H2 --> 2H+ + 2e-

and the reaction at the cathode is : oH- + e- + H+ ---> H20

          at anode        H2 --> 2H+ + 2e-

         at cathode      2OH- +2e- + 2H+ ---> 2H20

                            --------------------------------------------------

                               2OH^- + H2 ----------> 2H2O   overall balanced reaction
