Method: 2 to 3 spatula measure of Manganese (IV) oxide into CONICAL FLASK.
Assemble the apparatus: Includes Conical flask, thistle funnel, gas jar, water (tub?), delivery tube
Pour 20cm3 of hydrogen peroxide solution into thistle funnel.
Allow bubbles of gas to escape from delivery tube (15-30 seconds) then collect five test tubes of oxygen by displacement of water.
Experiment: HYDROGEN PEROXIDE SLOWLY DECOMPOSES TO FORM OXYGEN GAS AND WATER. THIS EXPERIMENT IS USED TO OBTAIN OXYGEN IN A LAB. A CATALYST ( manganes (IV) oxide) SPEEDS UP THE PROCESS.
