AIPMT MAIN 2008 Chemistry Standard Electrode Potentials MCQ Question
On the basis of the following E° values, the strongest oxidizing agent is [Fe(CN)₆]³⁻ → [Fe(CN)₆]⁴⁻ + e⁻; E° = -0.35 V Fe²⁺ → Fe³⁺ + e⁻; E° = -0.77 V
[Fe(CN)₆]³⁻
[Fe(CN)₆]⁴⁻
Fe²⁺
Fe³⁺
Correct Answer
Detailed Explanation
The strongest oxidizing agent is the one with the highest reduction potential. Here, [Fe(CN)₆]³⁻ has a higher E° value compared to Fe²⁺, making it the stronger oxidizing agent.
