Potassium permanganate is an inorganic chemical compound and medication. It is a strong oxidizing agent. KMnO₄ is a salt consisting of K⁺ and MnO₄ ^-1  ions and has the chemical formula KMnO₄. It dissolves in water đồ sộ give intensely pink or purple solutions. In Solid-state it forms prismatic purplish-black glistening crystals.

Sodium sulfite (sodium sulfite) is a soluble sodium salt of sulfurous acid (sulfite) with the chemical formula Na2SO3. It is a product of sulfur dioxide scrubbing, a part of the flue-gas desulfurization process. It is also used as a preservative đồ sộ prevent dried fruit from discoloring, and for preserving meats. It is also used in the same way as sodium thiosulfate đồ sộ convert elemental halogens đồ sộ their respective hydrohalic acids, in photography, and for reducing chlorine levels in pools.

Sulfuric acid is a mineral acid with molecular formula H₂SO₄. It is a colorless, odorless, and syrupy liquid that is soluble in water. In this reaction, it acts as an acidic medium only.

Sodium sulfite reacts with potassium permanganate and sulfuric acid

The Sodium sulfite reacts with potassium permanganate and sulfuric acid to sườn the potassium sulfate, Manganese(II) sulfate, water as well as sodium sulfate. The skeleton reaction –

KMnO₄ + H₂SO₄ + Na₂SO₃ = K₂SO₄ + MnSO₄ + Na₂SO₄ + H₂O

Now by using the ion-electron method we can balance the Oxidation-Reduction reaction.

Ion-Electron method

The Ion-electron method is a very effective method đồ sộ balance equations of the Redox reactions.

from the skeleton reaction, we can see that –

Here,

The Oxidizing agent: KMnO₄ or MnO₄^-1
The Reducing agent:  SO₃^2-

Reduction Half Reaction:

MnO₄ ^-1 +5e + 8H⁺  = Mn^2- + 4H₂O … …. …. …. (1)

Oxidation Half Reaction:

SO₃^2- – 2e + O^2- = SO₄^2- … … … … (2)

equation (1)x2 + (2)x5,

2MnO₄ ^-1 +10e + 16H⁺  = 2Mn^2- + 8H₂O

5SO₂^2- – 10e + 5O^2-= 5SO₄^-2

2MnO₄ ^-1 + 16H⁺ + 5SO₃^2- + 5O^2-=  2Mn^2- + 8H₂O + 5SO₄^-2

⇒ 2MnO₄ ^-1 + 6H⁺ +10H⁺ + 5O^2-+ 5SO₃^2- =  2Mn^2- + 8H₂O + 5SO₄^-2

⇒ adding necessary ions and radicals we get,

⇒ 2KMnO₄ + 3H₂SO₄ + 5H₂O + 5Na₂SO₃ =  K₂SO₄ + 2MnSO₄ + 8H₂O + 5Na₂SO₄

⇒ 2KMnO₄ + 3H₂SO₄ + 5Na₂SO₃ =  K₂SO₄ + 2MnSO₄ + 5Na₂SO₄ + 3H₂O
