Ncert Exercises & Solutions

For testing halogens in an organic compound with AgNO₃ solution, sodium extract (Lassaigne's test) is acidified with dilute HNO₃. What will happen if a student acidifies the extract with dilute H₂SO₄ in place of dilute HNO₃?

On adding dilute H₂SO₄ for testing halogens in an organic compound with AgNO₃, white precipitate of Ag₂SO₄ is formed. This will interfere witht he test of chlorine and this Ag₂SO₄ may be mistaken for white precipitate of chlorine as AgCl. Hence, dilute HNO₃ is used instead of dilute H₂SO₄.
