How long would it take to deposit 0.08g of copper from CuCl2 solution by passing a current of 0.5A?
[Cu = 64, F = 96500 C mol-1]
  • A.
    6 mins
  • B.
    8 mins
  • C.
    24 mins
  • D.
    48 mins
Correct Answer: Option B
Explanation

Cu2+ + 2e → Cu(s)
2 * 96500C deposit 64g of Cu
∴ x quantity of electricity wil deposit 0.08x = (2 * 96500 * 0.08)/64 =241.25 coulomb.
Q = It
241.25 = 0.5t
t = 241.25/60 = 8 mins
