Question

Balance the chemical equation potassium dicromate reacts with sulphur dioxide?​

Answer 1

SO2 + K2Cr2O7 + 3H2SO4 → K2SO4 + Cr2(SO4)3 + 3H2O. Sulfur dioxide react with potassium dichromate and sulfuric acid to produce potassium sulfate, chromium(III) sulfate and water. Sulfuric acid - diluted solution.

Answer 2

Answer:

Sulphur dioxide  gas changes acidifed Potassium Dichromate solution from orange to green.

Chemical reaction:

Sulphur dioxide reacts with acidified potassium Dichromate solution to give Chromium Sulphate , Poatssium sulphate and water.

3SO₂(g) + K₂Cr₂O₇(aq) + H₂SO₄(aq) → Cr₂(SO₄)₃ (aq) + K₂SO₄ (aq) +H₂O(l)
