Question

If in sodium salt 'A' anion have oxidation state of central atom is +3. Salt 'A' react with conc. H₂SO₄ and produce two gaseous product (no one is SO₂). Select the CORRECT alternative about salt 'A' :-

• A. Salt(aq) 'A' + KMnO₄/H⁺ $\xrightarrow[Δ]{60°}$ brown ppt.
• B. Salt(aq) 'A' + FeCl₃ → deep red colour sol. neutral sol.
• C. Salt(aq) 'A' + dil.H₂SO₄ → no observable change
• D. Salt 'A' contains CH₃COO⁻ anion

Answer 1

Answer: (B)

Salt(aq) 'A' + FeCl₃ → deep red colour sol. neutral sol.

Answer 2

The deep red color with FeCl₃ is a characteristic test for acetate ions. Therefore, the correct alternative is that salt 'A' reacts with FeCl₃ to produce a deep red color solution in a neutral solution, indicating the presence of acetate ions.
