Yes. Metal compounds often speed up its decomposition, but it is unstable and will decompose on its own (especially if heated or exposed to light). In addition, there could be impurities in the H2O2 or dirt on your glassware that is catalyzing the decomposition...or even catalase from bacteria - many, many causes.

Hydrogen Peroxide is H202 which potential that's already 2 factors oxygen. HP is used in hairdressing as a potential of offering colour into hair or to get rid of colour molecules from the hair. the better the concentration - the swifter this technique works. you are able to test via timing the oxygenation technique (ie how long it takes darkish hair to lighten and which concentration yields the appropriate effects). i've got merely examine Oracle2Worlds answer and now i've got self belief insufficient!!!
