During electrolysis of waterAt Cathode 4H+ + 4e- → 2H2At Anode 4OH- → 2H2O + O2 + 4e- 4 moles of electrons = 4 F electricity = 4eq of each gas is liberated.1 eq of H2 = 11.2 lit at STP4 eq of H2 = 4 x 11.2 lit = 44.8 lit1 eq of O2 = 5.6 lit at STP4 eq of O2 = 4 x 5.6 lit = 22.4 litTotal volume of both gases = 44.8 + 22.4 = 67.2 lit.
