   Number of electrons gained by the cathode must be equal to the number of
   electrons lost by the cahode. 
   
   
    
   
   
   At Cathode, 
   
   
   4H+ + 4e- --> 4H
   
   
   2H + 2H -->2H2
   
   
   
   At Anode,
   
   
   4OH - - 4e- --> 4OH
   
   
   2OH + 2OH -->2H2O + 2O
   
   
   O + O -->O2
