Answer: oxidizing agent:
reducing agent:
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
On reactant side:
Oxidation state of magnesium = 0
Oxidation state of chlorine = 0
On product side:
Oxidation state of magnesium = +2
Oxidation state of chlorine = -1
The oxidation state of chlorine reduces from 0 to -1, it is getting reduced. The substance which gets reduced, oxidize others and called as oxidizing agent.
The oxidation state of magnesium increases from 0 to +2. Thus, it is getting oxidized. The substance which gets oxidized, reduces others and called as reducing agent.
The balance chemical equation is follow,
2 I⁻ + SO₄²⁻ + 4 H⁺ → I₂ + SO₂ + 2 H₂O
According to this reaction, 2 moles of I⁻ reacts with 1 mole of SO₄²⁻ to produce 1 mole of I₂ and 1 mole of SO₂.
Result:
So with the formation of 1 mole of I₂, 1 mole of SO₂ is produced.
