AIPMT MAINS 2011 Chemistry Redox Reactions MCQ Question
A solution contains Fe²⁺, Fe³⁺ and I⁻ ions. This solution was treated with iodine at 35°C. E° for Fe³⁺/Fe²⁺ is +0.77 V and E° for I₂/2I⁻ = 0.536 V. The favourable redox reaction is
I⁻ will be oxidised to I₂
Fe²⁺ will be oxidised to Fe³⁺
I₂ will be reduced to I⁻
There will be no redox reaction
Correct Answer
Detailed Explanation
For I⁻ → I₂, the value of E° is positive, indicating a favorable redox reaction.
