Hands down, one of the best chemistry/science videos i have ever seen. Nice work. The music was spot on. W special emphasis to the pipette filtration segment as well as the dissolving of the residue in the bowl w the stirrer going . Thank you Astral 💚

Extremely useful material here. Surely appreciate it!

Amazing!!!! You are the first amateur chemist I have seen attempt this!! This catalyst is so cool and I have been wanting to have some for quite a long time.

First! :P We discovered that we have been running a lab for years without having sodium chloride. But a good chemist always has some sodium and chlorine gas, am I right?

Thank you for your high quality videos. A joy to watch.

This is so cool!!! I've been doing a lot of experimenting with platinum catalytic propane heaters lately, and I've always wondered if it would be possible to make one myself. After watching your video it definitly appears to be feasible! A friend of mine recently opened up a small automobile catalytic converter with an acetylene torch, and obtained the ceramic honeycomb inside. When I decide to chemically process it, instead of trying to obtain a bead of the metals it contains I may just keep them in solution and apply them to some quartz wool like you did here. Thanks for the inspiration!

Thank you for showing us this process and your methodology! Pt is a pretty mysterious and amazing element.. Put a Pt/Nb sheet in a wood smoke stream and you can smell all the transformed compounds produced by it (consumes it, though..)

I've finally got everything I need to try this, the last piece of the puzzle was the platinum, which I found in a broken R type thermocouple in a skip bin, from what I've read the negative leg is 100% platinum and the positive leg is 87% platinum/13% rhodium

Really nice video. I'd just recommend you adapt the volume of music and voice a bit, when the music comes, I have to turn down the volume so much that later I can't hear the voice...

Awesome video!!!

nice job/ used far less matal than i imagined

Hi! Great channel! What hot plate stirrer do you use or recommend? I'm torn between hot plates and people give mixed reviews.

Is it possible to use aluminum silicate ceramic wool in stead of the quartz wool?

Hi have you considered using a tilly lamp mantle thats 99% thorium dioxide as a catalyst? that was the other catalyst used industrially when pt ran short in ww1. my research gives 11 parts ammonia gas 89 air run through preheat 700c and use gasflow to push the exothermic catalyst temperature to 800-850c. Above 900, selectivity is reduced. thorium ran at atmospheric pressures, pt 4-5atm. 2 cooling chambers are used, 1 has water vapour added, one has o2. but we can use h2o2 bubbler instead. Apart from its fragility i think the tilly lamp mantles may be ideal, for surface area and contact times, easy to apply and clamp to a tube etc

Nickel and Cobalt can catalyze the oxidation right?

What should be the concertation of nitric acid ? And other acids you used ?

Can i use small alumuminum oxide balls instaed of quartz wool?

killer intro!

can i do this via kcl and potassium hexachloroplatinate?

cool

I think you can help me, can the rhodium chloride precipitated in water regia be taken directly to melting with a blowtorch? palladium I've already got it, but rhodium hasn't.

Big thumbs up for showing the process, we are currently purifing crude platinum for exactly this process (But we need a lot of time for editing...) But please make your videos a bit shorter and to the point if you can (:

Hi I tried to replicate the experiment but I didn't work, the resulting platinized quartz wool doesn't catalize the combustion of my burner, I really appreciate your help

Is it possible to use the same route,to produce a gold catalyst?

I tried adding ascorbic acid but nothing happens.

Surely a stupid question but at 8.07 and at 8.16 I cannot tell if you are adding water or blowing air into the solution. Is it water or just air or both ?

Good job but I was wondering if there is anything that can be used instead of quartz wool or maybe the honey comp of the catalytic converter can be used as it is

Ostwald Oxidation got taken down!! Was using that vid for photography chemistry synthesis from natural materials, can I get a link elsewhere or reupload/file ? Was greatly valuable and now i'm out in the water

Can Senku borrow some platinum from u to save the world?

Do you have any way to contact you?

Guys, the song is cool, let it be

platinum seem waste a lot in solution?

great video, not sure how you got 1mg as an excess of NaCl though. 20mg/195ram=0.1mmol Pt 0.1mmol x 2shoichiometry x 58.5rmmNaCl = 11.7mg NaCl edit: you allso say "0.42 mg of sodium chloridde"

If I just had the platnium ....or the nitric acid...or a beaker..

i have bought 5 grams fused quartz wool it cost me 40 dollars 😁

الحرارة تضر المحلول!

Great video, all except the unexpectedly annoying and loud music >_

Interesting video but for the love of all that you care about, adjust the volume of that crappy music you use without any kind of logic at 11:20 or so and in some other videos of yours. You go through long stretches of relatively quiet or even silent footage then suddenly, insanely louder techno music destroy your eardrums, especially if you use headphones (I do)...

Im honestly just here to know what the fuck is going on in dr stone

Washington dc will be completely leveled to the ground
