Answer»

solution:

So₂ +  Fe⁺³  → So₄²⁻ + Fe²⁺

Here, O.N of So² is increasing, so, their is oxidation of So₂

similarly, O.N of Fe⁺³ is decreasing. so, their is Reduction of Fe⁺³

OXIDATION HALF:

So₂   →     So₄²⁻

=>    So₂  +  2H₂O   →  So₄²⁻  [Balancing Oxygen]

=>     So₂  +   2H₂O    →   So₄²⁻   +   4H⁺ [Balancing HYDROGEN]

=>     So₂   +   2H₂O    →    So₄²⁻   +   4H⁺   +  2e⁻  [Balancing charge]...(1)

REDUCTION HALF :

Fe³⁺   →   Fe²⁺

=>   Fe³⁺   +  e⁻   →  Fe²⁺  [Balancing charge]

=>   2Fe³⁺   +  2e⁻   →    2Fe²⁺ [Multiplying by 2]...(1)

ADDING 1 & 2

So₂  +  2H₂0  +  2Fe⁺³  +  2e⁻    →   So₄²⁻  +  4H⁺  +  2e⁻  +  2Fe²⁺

So₂  +  2H₂0  +  2Fe⁺³     →   So₄²⁻  +  4H⁺  +  2Fe²⁺ [All things GET balanced]
