H2O2 (Hydrogen Peroxide) catalysis in clear plastic bottle? I am buying some 30% H2O2 which will be in probably black HDPE bottles. If I want to make some 3% - 5% solution, can I store that in clear bottles? How much faster will it catalyse versus having it in a dark bottle?

Will shelf life be significantly shorter? How much effect does sunlight (or other light) have on the H2O2 solution? Any way to measure this?

Regards,
An easy test for this would be to react H2O2 with yeast or baking soda (sodium bicarbonate) before and after sun bathing. Or you could simply measure gas production in the sun vs in a box for say 24 hours.

An easy way to measure the O2 released is to use a closed vessel with a ballon, but the more scientific method uses an inverted, graduated column.



You can measure light intensity with a photometer.
