Which of the following is a true structure of H2O2 in solid phase ? (a) (b) (c) (d)

124. When CO2 is bubbled through a solution of barium peroxide in water (a) carbonic acid is formed (b) H2O2 is formed HYDROGEN 16 (c) H2O is formed (d) Barium hydroxide is formed. 2 2 2 3 2 2 BaO H O CO BaCO H O -> 125. The oxide that gives hydrogen peroxide on treatment with a dilute acid is (a) PbO2 (b) Na2O2 (c) MnO2 (d) TiO2 2 2 H O can be prepared by- 1. Mercks method- 2 2 2 4 2 4 2 2 Na O H SO Na SO H O -> 2. Laboratory method- 2 2 2 4 4 BaO .8H O H SO BaSO -> 2 2 2 H O 8H O Therefore, option b is correct.
