Type: MCQ-conceptual-Medium-Class 12

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

A

I⁻ will be oxidised to I₂

B

Fe²⁺ will be oxidised to Fe³⁺

C

I₂ will be reduced to I⁻

D

There will be no redox reaction

Correct Answer

Option A

Detailed Explanation

For I⁻ → I₂, the value of E° is positive, indicating a favorable redox reaction.
