In a test tube containing a salt, a few drops of dilute H₂SO₄ was added, which gave colourless vapours having the smell of vinegar. The vapours turned the blue litmus paper red. Identify the correct anion from the following:

Solution & Explanation

Related Formula
CH₃COO^- + H^+ arrow CH₃COOH(g) (vinegar smell)
Core Logic

Reaction of salt with dilute H₂SO₄ liberating acidic acetic acid vapours (CH₃COOH) indicates the presence of Acetate ion (CH₃COO^-).

Step 1: Conclusion

Anion is Acetate (CH₃COO^-).

Pattern Recognition

Vinegar smell + dil H₂SO₄ reaction is the characteristic test for acetate ions.
