Consider the following reduction processes Z n 2 + + 2 e - → Zn s ; E o = - 0 . 76 V C a 2 + + 2 e - → Ca s ; E o = - 2 . 87 V M g 2 + + 2 e - → Mg s ; E o = - 2 . 36 V N i 2 + + 2 e - → Ni s ; E o = - 0 . 25 V The reduction power of the metals increases in the order

Options

  1. AC a < Z n < M g < N i
  2. BN i < Z n < M g < C a
  3. CZ n > M g < N i < C a
  4. DC a < M g < Z n < N i

Correct answer

B. N i < Z n < M g < C a

Step-by-step solution

Reducing power ∝ Tendency to undergo oxidation ∝ 1 reduction potential values So, reducing power decreases as C a > M g > Z n > N i
