When CO ₂ is bubbled through a solution of barium peroxide in water then

Options

  1. Acarbonic acid is formed
  2. BO ₂ is released
  3. CH ₂ O ₂ is formed
  4. Dno reaction occurs

Correct answer

C. H ₂ O ₂ is formed

Step-by-step solution

When CO ₂ is passed through aqueous solution of BaO ₂, BaCO ₃ is precipitated and H ₂ O ₂ is formed. BaO ₂+ CO ₂+ H ₂ O BaCO ₃ + H ₂ O ₂ H ₂ O ₂ can also be prepared by reaction of H ₂ SO ₄ with hydrated barium peroxide. BaO ₂ 8 H ₂ O + H ₂ SO ₄ BaSO ₄+8 H ₂ O + H ₂ O ₂
