= 1 x 1
= 1 mol
CrCl₃ ⇆ Cr³⁺ + 3Cl⁻
1 mol 1 mol 3 mol
Cr³⁺ + 3e → Cr
1 3 1 mol
mol Cr = 1 mol
massa Cr = mol x Ar
= 1 x 52
= 52 gram
e = Ar/muatan
= 52/3
e • I • t
W = _______
96500
52/3 • 6 • t
52 = _________
96500
52 • 2 • t
52 = _________
96500
1 • 2 • t
1 = _________
96500
2t = 96500
t = 48250 detik
Jadi, waktu yang dibutuhkan adalah 48250 detik
