Question

Name the anion [negative ion] present in the following compound:
Compound D when warmed with dilute H₂SO₄ give a gas which turns acidified potassium dichromate solution green.

Open in App

Solution

Sulphite or bisulphite anions react with dilute sulphuric acid to give sulphur dioxide gas, which turns acidified potassium dichromate (K₂Cr₂O₇) solution green.

M₂SO₃ + H₂SO₄ → M₂SO₄+ H₂O + SO₂
2MHSO₃ + H₂SO₄ → M₂SO₄ +2H₂O + 2SO₂
