My science teacher made us do an experiment where we added liver to hydrogen peroxide. Now I have to figure out a way to capture the Oxygen put off by the chemical reaction. I don't actually have capture the gas just say how I would... There are no limits in materials but I have to capture PURE oxygen (no air) and cannot use a balloon! PLEASE HELP ME SCIENTISTS AND OTHER SMART PEOPLE!!!!

use two test tubes. fill one with water, then turn it upside down in a bath of water. then connect the two test tubes with a tube (like a hose). put the hydrogen peroxide and liver in the other test tube then quickly close it off with the othr hose like tube... the oxygen will go into the test tube and the water will come out because oxygen is lighter than water... sorry i suck at explaining but u can just show this buy using a labelled diagram

Use water displacement.
Bubble the oxygen into a bottle (upside down) filled with water. The oxygen will replace the water. Cover the bottle and remove from the water. You now have a bottle full with pure gas

Probably the best way is to use electrolysis and collect the gases over the electrodes with inverted test tubes or so.
The Oxygen will be collected over one of the electrodes (don't recall which right now).
