The amount of electricity required to produce one mole of copper from copper sulphate solution will be

  • A
    1 Faraday
  • B
    $2.33$ Faraday
  • Correct answer
    C
    2 Faraday
  • D
    $1.33$ Faraday

Solution

In $\mathrm{CuSO}_{4}$ solution, oxidation state of $\mathrm{Cu}$ is $+2 .$ Hence one mole of copper sulphate will require charge equal to two moles of electrons to form metallic Cu. Mole charge = IF. Hence 2 Faraday is required.

Hence, the correct answer is option: 'C'.
