Genie in a Bottle | Experiments | Steve Spangler Science

Hydrogen peroxide is not a very stable compound and its decomposition can be induced by many means. Light will decompose it, which is why it is sold in brown bottles in drugstores. The surface of manganese dioxide provides a particularly favorable environment to catalyze the decomposition, though the mechansim is somewhat poorly understood.

Can Hydrogen Peroxide Be Used to Remove Manganese and …

Peroxide did not oxidize the manganese and it created massive complications with chlorine used for disinfection. The chart above shows the manganese removal results from different injectants used. One interesting point about the chart, is that it takes over 100 minutes with chlorine to perfectly oxidize manganese.
