There are other examples of bubbling hydrogen peroxide. On a rough surface it bubbles heavily. When earrings are put into a hydrogen peroxide liquid, it bubbles for some time and then stops. As the surface area is more rough, it tends to react more with the peroxide. It is evident that rough surfaces and dust can act as catalyst of the above reaction. If there is any oxidized metal present in the earrings, then there is chance of it getting reduced by the hydrogen peroxide. Hence, it bubbles.
@locutis76 The Pt is the catalyst that releases oxygen and the oxygen floats to the top and it is constant.. rhodium and other platinum based metal will do this..I cant see silver releasing oxygen bubbles,..Would be nice in creating cheaper PEM cells
go outside and pick up any rock and try it see what happens..... post another vid if i'm wrong and like I said ALMOST everything bubbles in hydrogen peroxide.
Why is platinum detectable with a VLF metal detector but not with a Pulse Induction metal detector? This intrigues me, I tested it on the weekend with a PI detector for no signal at all. Amazing. I hope you can help..
@chopppacalamari ..I really dont know..But am assuming that it has to do with a weak eddy currents in the magnetic field and would need a Very low frequency to detect the platinum,.
platinum based metals can do this,like rhodium,and iridiom,.But are subject to poisoning.There are attempts to use polymers to make less expensivev PEM cells.That is a great question and the answer is being searched for and will be discovered by someone in their garage or some young person.Some person like you.
silver is also a catalyst

@xiobus its is used an industrial catalyst for the production of ethylene oxide and formaldehyde..

@HENDER460 and it wont bubble? The rock will not act as catalyst like platinum.
blueshadow1996 8 months ago
almost everything bubbles with hydrogen peroxide duhr!!!
HENDER460 8 months ago
@HENDER460 almost everything..not everything?This is constant unlike almost everything..Does it become a catalyst??You cant be certain..duhhh

@blueshadow1996 MMM that makes sense. Thanks.

only the platinum group, right :) ?

is platinum the only metal which catalysis this reaction and is not attacked ?

does it desolve the platinum
ineeddollars 2 years ago
no, platinum catalysis the reaction from h2o2 to o2 and h2o. it does not react with it, it only decomposing it by acting as an catalyst.
