Question

Minta tolong dijawab yah no 24, makasih

Answer 1

NiSO₄ --> Ni²⁺ + SO₄²⁻

katoda: Ni²⁺ + 2e --> Ni

I = 1,93 A
massa endapan = 0,58 gr
Ar Ni = 58
F = 96500
t = ?

---

t = (massa endapan x F) / (e x I)

e = Ar Ni / perubahan biloks = 58 / 2 = 29

t = (0,58 x 96500) / (29 x 1,93)
t = 1000 sc (C)
