AIPMT PRELIMS 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 Fe³⁺ → Fe²⁺ + e⁻, E° = -0.77 V
Fe³⁺
[Fe(CN)₆]³⁻
[Fe(CN)₆]⁴⁻
Fe²⁺
Correct Answer
Detailed Explanation
The strongest oxidizing agent has the highest reduction potential. [Fe(CN)₆]³⁻ has a higher E° value than Fe³⁺.
