Solution Summary

This solution describes the release of oxygen from the reduction of hydrogen peroxide.

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 ...
