Table of results from experiment Name of chemical Colour / texture Reaction when added to Hydrogen peroxide When tested for Oxygen When tested for Hydrogen When heated When heating test for Oxygen When heating test for Hydrogen Hydrogen Peroxide Clear Liquid N/A No reaction No reaction No reaction No reaction No reaction Copper Oxide Black powder No reaction No reaction No reaction Liquid bubbled Splint glowed brighter No reaction Magnesium Oxide White powder No reaction No reaction No reaction Liquid bubbled No reaction No reaction Zinc Oxide White powder No reaction No reaction No reaction Liquid bubbled No reaction No reaction Manganese Oxide Black powder Liquid bubbles up Lights glowing splint (oxygen present) Creates popping sound (Hydrogen present) NA N/A N/A From my table of results you can see that the only chemical to act as a catalyst and speed up the decomposition of Hydrogen peroxide was Manganese oxide. There is also a possibility that copper oxide might have shown another reaction. The effect of a catalyst on the decomposition of Hydrogen peroxide Aim: To find out which substances speed up the reaction sufficiently to produce enough oxygen to relight a glowing splint.
