Question

Write the redox reactions using half equations.

2Fe³⁺(aq) + 2e^–(aq) → I₂(s) + 2Fe²⁺(aq)

In the reactions given above, mention 

(i) Which reactant is oxidized? To what ?

(ii) Which reactant is the oxidizer?

(iii) Which reactant is reduced? To what?

(iv) Which reactant is the reducer?

Answer 1

2Fe³⁺ + 2e^– → 2Fe²⁺ (reduction), 

2l^– → I₂ +2e^– (oxidation) 

Fe³⁺ is reduced to Fe²⁺

I^– is oxidized to I₂

I^– is the reducer 

Fe³⁺ is the oxidizer.
