Hydrogen peroxide can be prepared in the laboratory by the action of dilute acids on metallic peroxide. In one method, sodium peroxide is added in samall amount at a time to a dilute solution of sulphuric acid in cold. Sodium peroxide can be replaced by barium peroxide. In this case, a paste of `BaO_(2).8H_(2)O` is prepared and added gradually to an ice-cold dilute sulphuric acid. Barium sulphate precipitates out leaving behind a dilute solution of hydrogen peroxide. Phosphoric acid can also be used in place of sulphuric acid. Which of the following is used for the preparation of `H_(2)O_(2)`?A. Anhydrous `BaO_(2)`B. Anhydrous `Na_(2)O_(2)`C. `TiO_(2)`D. `PbO_(2)`
