5.Detection of Sulphite: On adding dilute Sulphuric acid to a metallic Sulphite, a colourless gas having burning sulphur smell evolves which turns acidified Potassium dichromate solution from orange to green and Potassium permanganate solution from purple to colourless. Which of the following sets of balanced chemical equations correctly represents the reactions involved?
- A.Na₂SO₃ + H₂SO₄ → Na₂SO₄ + H₂O + SO₂; K₂Cr₂O₇ + 3SO₂ + H₂SO₄ → K₂SO₄ + Cr₂(SO₄)₃ + H₂O; 2KMnO₄ + 2H₂O + 5SO₂ → K₂SO₄ + 2MnSO₄ + 2H₂SO₄
- B.Na₂SO₃ + H₂SO₄ → Na₂SO₄ + H₂O + SO₃; K₂Cr₂O₇ + SO₃ + H₂SO₄ → K₂SO₄ + Cr₂(SO₄)₃ + H₂O; 2KMnO₄ + H₂O + 5SO₃ → K₂SO₄ + 2MnSO₄ + 2H₂SO₄
- C.Na₂SO₃ + H₂SO₄ → Na₂SO₄ + H₂O + S; K₂Cr₂O₇ + 3S + H₂SO₄ → K₂SO₄ + Cr₂(SO₄)₃ + H₂O; 2KMnO₄ + 2H₂O + 5S → K₂SO₄ + 2MnSO₄ + 2H₂SO₄
- D.Na₂SO₃ + H₂SO₄ → Na₂SO₄ + H₂ + SO₂; K₂Cr₂O₇ + 3SO₂ + H₂ → K₂SO₄ + Cr₂(SO₄)₃ + H₂O; 2KMnO₄ + 5SO₂ → K₂SO₄ + 2MnSO₄ + 2H₂SO₄
