What is the reaction of hydrogen peroxide to add manganese dioxide?
This problem is not easy to answer, the principle of manganese dioxide catalytic hydrogen peroxide I have not learned, but I have also considered, I think so, hydrogen peroxide and manganese dioxide first combination, the formation of permanganic acid, permanganic acid is a Very special acid is indeed present, it can not be stable under normal conditions, it will be further decomposition, the formation of manganese dioxide, oxygen and water
Hydrogen peroxide → water + oxygen (arrows on the manganese dioxide, as a catalyst)
There are bubbles produced
