A current of 1.93 ampere is passed through 200 mL of 0.5 M Zinc sulphate (aq.) solution for 50 min with a current efficiency of 80%. If volume of solution remain constant, then[Zn2+]after deposition ofZn2+is:

Options:

Answer:
A
Solution:

No. of Faraday=1.93×50×6096500=0.06
∴Moles ofZn2+deposited=80100×0.062=0.024
∴  Zn 2+  =  0.5 × 0.2 − 0.024 0.2 = 0.38 M
