Hydrogen Solved Examples | askIITians

This prevents the further reaction of the acid, i.e., causing the reaction to stop. If, however, hydrated barium peroxide (in the form of this paste) is used, the water causes to dislodge the insoluble. BaSO 4 from the surface of BaO 2. BaSO 4 thus settles at the bottom of the reaction vessle and the reaction continues without any difficulty.
