Salt ' $X^{'} +$ dil. $H_{2} SO_{4} \to gas (B) + H_{2} O$

Salt ' $Y^{'} +$ Con. $H_{2} SO_{4} \to gas (B) + (C) + H_{2} O$

(gas)

Then salt 'X' and 'Y' may contain anions respectively.

Answer:

Solution:

Dilute H₂SO₄ reacts with CO₃²⁻ to produce CO₂ gas (B). Concentrated H₂SO₄ reacts with C₂O₄²⁻ to produce CO₂ (B) and CO (C) gases.

Concepts: Anion reactions with dilute and concentrated sulfuric acid.
