What mass of Cu would be produced by the cathodic reduction of Cu $^{2+}$ when 1.60A of current passes through a solution of CuSO $_4$ for 1 hour. (F=96500Cmol $^{-1}$ , Cu=64)

A.

7.64g

B.

3.82g

C.

1.91g

D.

0.96g

View answer & explanation

Correct answer is C

M = $\frac{MmIT}{96500n}$

Where

M=mass

Mm = Molar mass = 64g/mol

I = current = 1.6A

T= Time =1h r=3600s

N= No of Charge = +2

M = $\frac{64x \times 1.6 \times 3600}{96500 \times 2}$

M=1.91g
