If I had a lab where I had hydrogen peroxide which is reduced in the presence of a catalyst to oxygen and water, how can I measure the amount of oxygen that would be released?© BrainMass Inc. brainmass.com October 9, 2019, 5:05 pm ad1c9bdddf
2 H2O2 ---------> 2 H2O + O2
Both hydrogen peroxide and water are liquids, yet oxygen is a gas. Therefore, if you connect the reaction vessel via a tube into another (upside down) vessel that contains water, then water will be displaced during the reaction as a result of the oxygen gas coming from the reduction of hydrogen peroxide. If you use a graduated cylinder or something similar, all you've got to do is read the initial volume in the cylinder, and then the final volume. The ...
This solution describes the release of oxygen from the reduction of hydrogen peroxide.
