Reaksi di Katoda 2H₂O + 2e ==> 2OH⁻ + H₂
Reaksi di Anoda 2H₂O ==> 4H⁺ + 4e + O₂
diketahui
i = 10 A
t = 2 jam = 7200 detik
mol elektron = it/96500
= 10 x 7200/96500
= 0,746 mol
*) Volume gas di Anoda
2H₂O ==> 4H⁺ + 4e + O₂
Menurut reaksi di anoda di dapat bahwa mol gas O₂ = 1/4 mol elektron
mol
mol gas O₂ = 1/4 x 0,746 mol
= 0,1865 mol
Keadaan STP ( 0°C , 1 atm )
maka
Volume gas O₂ = mol x 22,4
= 0,1865 x 22,4
= 4,178 Liter
*) Volume gas di Katoda
2H₂O + 2e ==> 2OH⁻ + H₂
Menurut reaksi di katoda di dapat bahwa mol gas H₂ = 1/2 mol elektron
mol
mol gas H₂ = 1/2 x 0,746 mol
= 0,373 mol
Keadaan STP ( 0°C , 1 atm )
maka
Volume gas H₂ = mol x 22,4
= 0,373 x 22,4
= 8,3564 Liter
Semoga dapat membantu yah kak
