A member asked:
Why does hydrogen peroxide bubble when it is applied to a wound? just applied some to a cut, and it bubbled up and formed a crusty layer on it.
A doctor has provided 1 answer
Hydrogen Peroxide: Blood & cells contain catalase. This enzyme is released in wounds. Catalase + hydrogen peroxide (H2O2) = water (H2O) + Oxygen (O2). The foam/ bubbles that arise are oxygen.
