Question

A solution contains Fe²⁺, Fe³⁺ and I^$-$ ions. This solution was treated with iodine at 35^oC. E^o for Fe³⁺/Fe²⁺ is + 0.77 V and E^o for I₂/2I^$-$ = 0.536 V.
The favourable redox reaction is

I₂ will be reduced to I^$-$

there will be no redox reaction

I^$-$ will be oxidised to I₂

Fe²⁺ will be oxidised to Fe³⁺
