Fekauʻaki mo e electrolysis ʻo e vai, ʻoku aʻusia ʻa e vaeua ʻo e vai ki he ʻosikena mo e fakapaaki ʻo e ʻi hono tufaki ha ʻuhila ʻi he vai.
ʻI he vai maʻa ʻi he cathode kovi, ʻoku hoko leva ha tali ʻoku holo ʻi he feituʻu electrons (e −) mei he Cathode ʻoku foaki ki fakapaaki ʻo e cations koeʻuhi ke fakapaaki ʻo e e ngaahi foomu kasa. ʻI he anode lelei ko ʻeni, ʻoku hoko ai ha tali oxidation, ʻa ia ʻoku ne ʻomi ʻa e kasa ʻo e ʻosikena lolotonga ia ʻoku ne ʻoange electrons ki he anode. ʻOku ʻuhinga ʻeni, ko e ngaue ʻa e vai ʻi he anode ke faʻu ʻaki ha ʻosikena pea tukuakiʻi lelei fakapaaki ʻo e ions (protons). Ko ia ʻoku fakakakato ai ʻa e oma pasikala ko ʻeni ʻo e palanisi ʻo e ivi:

2H ʻoku ou ʻiloʻi+ (aq) + 2e → H2 (g) (fakasiʻisiʻi e cathode)

Tali fakalukufua: 2H ʻA IA2O (l) → 2H2 (g) + O2 (g)

ʻOku faʻa fakaʻaongaʻi ʻa e vai ʻalakalaine ki he electrolysis kae lava ke ngaohi fakapaaki ʻo e.

Ki he eletcrolysis, ʻoku fakaʻaongaʻi pe ʻa e concentrations ʻo e 20% ki he 40% caustic fakaleleiʻi.

The ultrasonic probe of the high-performance ultrasonicator UIP2000hdT functions as anode. Due to the ultrasonic field applied, the electrolysis of hydrogen is promoted.
