Which of the following anion does not produce ppt with $BaCl_{2}$ solution however gives ppt with $AgNO_{3}$ solution.

Answer:

Solution:

In salt analysis, check the reaction of anions with BaCl₂ and AgNO₃.

CO₃²⁻ and C₂O₄²⁻ give precipitate with BaCl₂.

NO₃⁻ does not give precipitate with either BaCl₂ or AgNO₃.

S²⁻ does not form precipitate with BaCl₂ (BaS is soluble) but gives black ppt of Ag₂S with AgNO₃.

Therefore, the correct anion is S²⁻.
