Question

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, C a Z n M g N i, N i Z n M g C a, Z n > M g N i C a, C a M g Z n N i

MARKS App · Accepted Answer

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