Question

The strongest oxidizing agent among the species In³⁺ (E° = -1.34V), Au³⁺ (E° = 1.4V), Hg²⁺ (E° = 0.86V), Cr³⁺ (E°=-0.74V) is
(a) Cr³⁺
(b) Au³⁺
(c) Hg²⁺
(d) In³⁺

Answer 1

since oxidising power is directly proportional to E not reduction
then Au 3+ is answer

Answer 2

The strongest oxidizing agent among the species

In³⁺ (E° = -1.34V), Au³⁺ (E° = 1.4V), Hg²⁺ (E° = 0.86V), Cr³⁺ (E°=-0.74V) is Au³+.

Hope the student can provide better choice for the student to move forward and well prepare in a fine manner.

This will provide better choice with no risk and trouble of it.
