Question
A current of 1.6 A is passed through a solution of CuSO4. How many Cu++ ions are liberated in one minute? (Electronic charge= 1.6 x 19-19 C)
3 × 1020
3 × 1010
6 × 1020
6 × 1010
Solution
A.
3 × 1020
Given:- Current - 1.6 A
t = 1 × 60s = 60 s
Charge flowing in one minute
q = I × t
= 1.6 × 60
Charge required to liberate one copper ion 2C
Number of Cu2+ liberated
=
= 3 × 1020
