Electrolysis of Water

When electrolysis is performed using a dilute aqueous NaOH solution as an electrolyte, hydrogen gas is generated at the cathode (-), and oxygen gas is generated at the anode (+). The reaction equation is as follows.

(+)pole: 2OH- → H2O + 1/2 O2 + 2e
(-)pole: 2H2O + 2e → H2 + 2OH-
