Addition of H 2 SO 4 to BaO 2 produces

Options

  1. ABaO , SO 2 and H 2 O
  2. BBaHSO 4 and O 2
  3. CBaSO 4 , H 2 and O 2
  4. DBaSO 4 and H 2 O 2

Correct answer

D. BaSO 4 and H 2 O 2

Step-by-step solution

Acidifying barium peroxide and removing excess water by evaporation under reduced pressure gives hydrogen peroxide. BaO 2 . 8 H 2 O s + H 2 SO 4 aq → BaSO 4 s + H 2 O 2 aq + 8 H 2 O l This is a common method to prepare hydrogen peroxide
