Cl 2 g + Ba OH 2 → X aq. + BaCl 2 + H 2 O X + H 2 SO 4 → Y + BaSO 4 Y → Δ > 365 K Δ Z + H 2 O + O 2 Y and Z are respectively :

Options

  1. AHClO 4 ,   ClO 2
  2. BHClO 3 ,   ClO 2
  3. CHClO 3 ,   ClO 6
  4. DHClO 4 ,   Cl 2 O 7

Correct answer

B. HClO 3 ,   ClO 2

Step-by-step solution

6 Cl 2 + 6 Ba OH 2 → Ba ClO 3 2 + 5 BaCl 2 + 6 H 2 O X Ba ClO 3 2 + H 2 SO 4 → 2 HClO 3 + BaSO 4 ↓ Y 2 HClO 3 → Δ > 365 K Δ 2 ClO 2 + H 2 O + 1 2 O 2
