Anhydrous barium peroxide forms a coating of insoluble barium sulphate on its surface, which stops further action of the sulphuric acid. In contrast, using hydrated barium peroxide \left(\mathrm{BaO}_2 \cdot 8 \mathrm{H}_2 \mathrm{O}\right) allows for the reaction to continue, as the presence of water in the compound facilitates the reaction with sulphuric acid.
