The bonds that hold H2O2 together break apart and the atoms are rearranged to form water (H2O) and oxygen (O2) molecules. This happens slowly in store-‐bought hydrogen peroxide, so even in dark bottles, it will 'expire' in a year, or less if it's opened. ... And higher concentrations of H2O2 produce more oxygen.
