You should drop powdered platinum into the hydrogen peroxide. Or, not. It's very dangerous and you'd waste a lot of platinum when the reaction shoots out of the top of the beaker..

Thanks.as a result of oxidation with hydrogen peroxide. can platinum be precipitated?

I dissolve the catalyst in Aqua Regia solution. after finishing the work : I add zinc to it. The reaction is highly calorific but does not precipitate When I add sodium bohydride, nothing precipitates, and when I add more, a white jelly-like substance precipitates. When I add aluminum to it, the reaction is very hot, but I have a black and purple deposit. Exactly how should I separate palladium, platinum and rhodium from the solution. Rhodium is not important to me right now. How do I separate platinum and palladium from Aqua Regia solution?

Does this also decompose the platinum? Which decomposes the hydrogen peroxide more vigorously, platinum or silver?

Thanks for sharing this video! I've got a question, does the platinum get consumed by the reaction? So do you have to change the platinum after some time for the decomposition of the hydrogen peroxide? thanks for answering!

No, the catalyst reaction is two part. First the extra oxygen in H2O2 prefers the bond with the metal forming a metal oxide (PtO). However, with further interaction with H2O2 an O2 bond is preferred to the metal oxide bond which releases the oxygen from the metal to form the common O2. No metal is consumed.

In the scheme at 1:15, as of what I know, O2 doesn't have a double bond and is a stable free radical, with each oxygen atom having an unpaired electron.

Your're right, that follows from the MO-diagram. In order to minimize confusion, we use the representation with the double bond, as long as we don't want to point out special reactivities.

Dip it in mineral acids, solvents, then torch it. Really depends on your dirt

unfortunately we have a different language. It's clear : - kzitem.info/news/bejne/p46HyIqcb4GjnJg but your not, it's not clear: - what substance is taken how it is not always clear if you post your machine text under the link ("description") below, it will be better. in languages there is a grammatical difference. but if there are formulas and the number(quantity) of substances taken, then immediately everything is clear.

Ok, we can do that. Well, the software we use is the best TTS program for free. As long as no one wants to donate money so that we can invest in a proper software we'll stick to this one.

Using the Schott Duran glassware made in Germany ( actually says West Germany on the beaker so it must be fairly old ) so I think it might be Chemplayer under a new identity.
