Thank you so much to the viewer who donated the bar. I really appreciate it.
Good to see your videos on a regular basis again. Damn, it's been quite a few years watching you. Hope you're doing good.
Hello I want to ask you please about a ion exchange separation vidio of two simular metal for example platinum and ruthinium

$180USD gift not bad
I want to see if you can oxidize it and then burn it and what color the flame is when you do?
Roughly cost $260 USD. Nice gift, donor!!
Probably a bit more. Small bars come at a significant premium over the spot price.
@@FrietjeOorlog The price I quoted was for a PAMP ingot with the same Lady Fortuna picture.

I need special tutorial . Email please
I always found it interesting how resistant the platinum series metals are, in addition to their beautiful, silvery color
The two are actually related, the atomic structure is so closely knit that it is almost a perfect reflection which makes it seem like a far more white/reflective surface than normal.
RIP NurdRage Channel. We will always remeber you.

The funny thing I remember watching that video and showing it to my grade school science teacher.
I miss when nurdrage would upload more often I hope everything things ok

RIP NurdRage. 😢
I'd love to see you make hydrogen peroxide
+1, definitely this (very interested in a catalytic method of doing this)
Yeah it would be extremely useful to be able to make large quantities of peroxide for making acids, cleaning, etc.. i have searched for how to make peroxide but no home chemists have successfully made it in useable amounts.. hopefully nurdrage does it, if anyone can do it it will be him.. hydroponics shops are the best place to buy it ( i have a 5 litre bottle at 50%) it but it's expensive, i think it was 60 bucks but that was a long time ago and it would have raised in price since then
Mark Short
FYI, you can freeze the water out of 3% peroxide and concentrate it all the way to 30%. Get a pop bottle and freeze it until it's a slush. Put the bottle in the refrigerator and invert over a container. The concentrated peroxide will slowly drip off the mass of ice crystals over the next hour or so, while the neck retains the ice. Repeat several times until you get to 30%. Alternatively, you can leave an open plastic bin full of peroxide in the closet for a few weeks and the water will preferentially evaporate. You'd be surprised how concentrated it can get. Peroxide can be made by electrolysis of ice cold dilute sulfuric acid solution or ammonium sulfate with non catalytic anode material(usually carbon), which is then distilled off under vacuum.
@@atari7001 Due to the differences in boiling points, I assume their volatilities are different enough at room temperature to evaporate much more water than peroxide, but is there a noticeable loss of peroxide anyway?
@@atari7001 And wait can you distill water out of it to concentrate it? Would that be dangerous?
It seems that another awesome RUclipsr has disappeared without explanation. Alas.
Hope that you come back someday.
Feel the same. This was my main link to chemistry since school a decade ago.
Click into his channel and go to the Community section; you'll get the explanation you're looking for. In short, lost his job and lost access to the lab he was using a year ago, and this is footage recorded before that happened that he edited and uploaded later.
He ran out of money for anything but simple videos you can do in your kitchen or whatever he doesn't have a lab, and probably doesn't want to do what happens if you combine coke and Mentos lol
We miss you
Thanks for all the great videos NurdRage. Your videos are what got me interested in chemistry in middle school. Now I’m finishing my chemistry degree. So thanks again for everything.
I love these inorganic/precious metal videos so much!!!
its nice to see you back making more videos
You could make organic catalysts with it. Seems like very interesting chemistry!
Gosh, it seems like with platinum group metals you can stitch pretty much any two organic pieces together. Getting your hands on palladium is soooo enviable. It seems like every third reaction in OrgSyn requires some awfully weird and stupidly expensive platinoid complex. I'd looove to actually see one of them!
@@elijahberegovsky8957 Yea indeed! I remember correctly some of the reaction conditions remain pretty harsh tho. There is also a lot to explore to what degree organic ligands influences reaction specificity and such.
I've been waiting on this for years!
How about a video on silver's resistance? For example, how it doesn't effectively dissolve in aqua regia, despite that being capable of dissolving gold, highlighting how the chloride inhibits any further oxidation as an effective rock paper scissors analogy.
Hi Nurd...
No, the rate of attack on Pt vs. Pd will not help what so ever with seperating both.
Platinum and Palladium I was like 90% sure that their chemical resistance were almost identical
But doesn't nitric acid attack Pd moderately, while having little to no effect on Pt?
I would love to see you alloy a small amount of Pt and Pd and then try to separate them. It seems to be very challenging.
If Ag is present in the alloy all 3 metals will be attacked by nitric acid alone. PGMs tend to follow Ag as well as each other . The extent to Pt dissolution depends on several reaction conditions. There is a lot of scientific literature on this phenomenon. Google "platinum silver nitric acid" and check the first result.
@@darrentoh9976 yeah...unfortunately platinum and palladium are NOTORIOUS for being able to be dissolved by nitric acid when alloyed together with silver or other platinum group metals. For example, a bar of 92% platinum and 8% silver will be dissolved by just nitric acid. It’s basically acting as the solid metal alloy version of an azeotrope. There are many others that exists that have a similar effect. I’d be willing to bet that a palladium/platinum alloy would suffer the same effect. Also, unless you’re working with known and verified pure 99.999% pure platinum or higher, many platinum sources and ores often have silver and other PGMs follow them through the refining process even when no silver is expected or known about in the sample, there’s usually always some there. You have to go through more rigorous chemical refining to deal with it.
Good to know. I will never approach my palladium collection with any nitric acid!
Thank you for this very interesting talk.
NurdRagd: gets expensive metal as gift
Also NurdRage: Let's stick it in acid and see what happens
Hope all is well. Thank you for the information and entertainment
I love these precious metal videos
First Sam o nella now NurdRage
I miss your videos, I’m back watching again now I used to watch these videos almost 11 years ago
It's been 5 months since you posted a video, are you OK man? Did you find a new job? Any progress on a new lab? Let us know what's going on please.
Nice video. Thank you sir.
Where did you go? I just found you and now I see you have not been on in 8 months.
I miss you NurdRage! 🥲
show us how to evaporate and crystalise
What do you mean.
in general, or with palladium chemistry?
gonna need a nuke to evaporate that pd !
You’re a chef watching chemistry vids, hmm, getting breaking bad vibes here
Nice video ! I really enjoyed watching this :)
Good job.
Really cool video, subbed after seeing it
great video sir, thanks for sharing this..
Palladium nitrates sound interesting. Want to see your vids on that👍
Wow! 😮🤩 Great content!
I'm glad I got your channel recommended by a nile red video
You can quantitatively precipitated Pd with dimethylglyoxime in acidic pH. Dissolve the DMG with NaOH then add to the Pd solution. Works well removing Pd contamination from Pt or other PGM
I congratulate you, brother.
You're a very good person and a chemical synthesis professional.
I wish I could communicate with you via email and thank you again 🌼
You are literally the man that inspired me to do chemistry experiments, so try to make new videos as soon as possible!
please, you are being missed 🙂
Yo, I am surprised how Nile Red used to be so happy when you commented on his video. Hope you get more subscribers!
It would be interesting to know more about catalyst chemistry.
Follow-up video on recovery of the dissolved metal!
Please update us with the palladium nitrate whenever you make use of it!
Wicked! Actually I read that refineries make a lot of use of electro chemical methods as well as elemental chlorine as reactant.
Give him a few months guys, he said he would take a break to play cyberpunk 2077 and borderlands 3 back in 2019 so he's prob just chilling out for a while.
LOL, yeah, that’s what I thought, after all it was released about the same time as this video, and he said he’d “vanish off the face of the Earth for a few months”.
I like your channel
True scientist.
Thanks for chipping in that bar. That was interesting. Be interesting to know how to recover the metal from solution.
Evaporate it down to 50% of its volume, add a few crystals of sodium chlorate followed by a few milliliters of saturated potassium chloride salt solution. This forms a beautiful red Potassium hexachloropalladate (K2(PdCl6)). There are several other ways as well. Since NR has a known pure Pd solution he could simply add Dimethylglyoxime to precipitate the Pd as a fluffy yellow mass. This complex can then be calcined to yield Pd metal. I've never tried it, but supposedly CO (carbon monoxide) will precipitate the metal directly.
on codyslab channel he has a precious metal recovery series and he precipitated palladium out of solution with a good explanation
A simple alternative would be to rely on the reactivity series. An addition of .999 Cu would displace the Pd and precipitate out a fairly clean palladium powder with minor copper contamination.
Hey Nurdrage, hope you are doing well. I’m working on building my supplies and glassware to start nickel plating steel parts. You should do a video series on making the required chemicals :) I’m just winging it from patents and RUclips. Nickel strips and sulfamic acid, boric acid and I have to get some battery acid and HCL to make nickel chloride. Also the crystals are an awesome green
I would really like to see a sandmeyer reaction!!! I haven't seen a decent one on here and I have a task which requires it..
Another fun fact. YT has vids of Nickel plated Aluminum foil (spark initiated) exothermically form NiAl alloy. Palladium-Aluminum ring was used in US interstages to explosively disconnect stages (yet the strong plated bond kept stages together).
please add more videos 😊😊😊
Thank you for the video. Can you please demonstrate with copper, aluminium and other conductive metals in relation to chemistry. I am interested in this area and want to learn where electric car Industry is heading, renewable energy and wiring
Awsome!
Nurdrage, I've been reading that you can't make sodium chlorate with electrolysis using gold electrodes like you did with platinum or MMO. I'm a bit surprised. I'd love to try it to see why but I don't have any pieces of gold big enough nor do I have the safety setup to deal with potentially toxic gold compounds. Would you mind making a video of such?
Would you please answer a question on persistence of late 18th and early 19th century pesticides? These are cabbage Looper treatments ingredients: lead arsenate, calcium arsenate. Are they still there? Can they accumulate in plants or water? And yes, I have Silent Spring, but I remember dimly it was all about -drin suffix chemicals.
Interesting.
Will u make a video about how to make potassium chlorate using lead dioxide electrodes and making PbO2 electrodes I dont know y my chlorate turned red or black by using lead dioxide and cadmium dioxide
Hey Nurdrage I was wondering if you could do a segments on ionic liquids? I have been trying to make a cheap ionic liquid based on zinc chloride and urea but have not been very successful. Can you help?
I'd love to see the palladium react with hydrogen and some experiments with the PdH_0.608 !
It turns grey and brittle, similar to TiH2.
@@Dmayrion2 The interesting part is, that Palladium reacts with hydrogen at room temperature, while titanium needs at least 300°C.
It would be interesting how to deal with H2O3Sn when you dissolve brass or tin in HNO3😉
Use it to create an " Arc Reactor"!! ?
Nice sir
How about using palladium as an anode just like you did for platinum?
Just started watching. My bets are on.. Electrolysis!! (Followed by Aqua Regia)
Hi sir can you help us to test or to determine palladium metal? because we have a suspected palladium metal weighing 15kilo grams
Sir plz video for
Iridium acid working and refining
I miss Nurdrage
Could you dissolve it and then try to make Pd/C, Pd powder or phosphine/Pd catalysts, etc?? Isn't PdNO3 a possible precursor to Pd powder or another compounds, or you need the "chlorine - palladium" compound like when dissolving gold in Aqua Regia? Or it does not form it and forms the nitrate anyway?
Have you done a video mixing manganese dioxide and hydrogen peroxide? What is the sicence behind it. There was a youtube video stating it is used to make a "something" that I wont type but goes bang
Cool. I bought a palladium ring back when it was $600/oz
didn't realize its been 9mo. hope all is good
hey i want to seperate dichloromethane and iso propyl alcohol from its mixture can you suggest me a distillation method?
Please be satisfied What acids that dissolve rhodium metal? And make a video explaining
To answer your question, yes using Nitric acid is a way to remove palladium from platinum.
Kind of like inquarting gold with silver or copper, the platinum content can’t be too high, but if you have Pt group metals it is best to put it all in Nitric acid first to remove palladium (or other base metals if present). Then decant off the solution, and you should just be left with other Pt group metals like platinum, osmium, iridium, etc and possibly gold if there was any.
Then dissolve the rest in aqua regia. And after that only very resistant metals like osmium, iridium and rhenium should be left.
Curious if the less attacking solution (H2O2) might have "softened it up" for the nitric acid to do a better job. Maybe providing some nucleation sites. Would be cool to see the difference between a new bar and the one treated with the lightly reactive solution. Can't afford to donate it though, so I'll just use my imagination xD. Thanks for all you do.
Hey I want to asked how we melt to gold in liquid shape and used for glass colours
A useful topic to do a video on would be how to bleach out or destroy aminopyralid contamination aka persistent herbicide out of soil or at least my compost. I am not a chemist but it would be swell if I could load my contaminated compost into a barrel and add bleach or some antidote that would break down the aminopyralid and any excess bleach just turn to salt. Also I could burn the compost down to biochar but is that enough to destroy the aminopyalid? Maybe we could nip this in the bud?
How can i make alumium powder via electrolysis? Also i have some powder but its unreactive as its oxidised. can i sucessfully remove the oxidation with citric acid?
(OFF TOPIC) Have you ever done a video on the synthesis of (K2S2O8) Potassium Persulfate? Would like to see that if possible.
So, there will be a part 2?
WOW!!! Such a nice present @_@!!!!!
You should use it to make a through hole activator, and then make some double sided PCBs with plated through holes.
So how come catalytic converters don't get eaten up with NO2 over time?
Do you know of any library of chemical reactions? Physical or digital.
what gases can i run through a simpler condenser for a solid product?
In theory if you used hot dilute nitric acid and dissolved the Pd until no more would go into solution, I'd assume you could cement it out on copper just like you can silver. If you had Pt that was alloyed with other metals. You might be able to inquart it with Pd to dissolve out those other metals if all of them were able to be dissolved by nitric acid. Silver might work though just as it does with gold refining. Those would be some expensive experiments if they messed up though.
I just saw that same kind of bar somewhere here on RUclips but I can't remember where
Future video idea. Recycling old plastics by vaporizing it and turning it back into a liquid to a basic chain sequence.
Hi Nurd We are wait evaporation
Sir.Pleas Tell me about Red Copper 8 sulfide.???
I've been looking for where Palladium is in the reactivity series of metals, but it doesn't look like it's included in the ones I've found so far. Does anyone know where it ranks?
Sir, I saw an old clip of you and you mentioned ammonia and it is a transparent liquid, please tell me how to get it and from where or how to make it with my own hands and I will be thankful to you
Supermarkets.
Hopefully your supermarket should stock it.. try the cleaning aisle.
Sir plsz iridium testing
can you make a catalyst head for a hand warmer with your paladium nitride solution?
Oh that would be cool
@@borttorbbq2556 i bought something like 15 hand warmer from 5different brand. most of them dont work that well, and if they do work they only last about 10uses before stopping working. this is very frustrating as the working principle is very simple, but they simply refuse to make them correctly. because it cost money.
i bought a real HAKKIN hand warmer. they are the one who started it all. it works great, but has a slightly lower output then my chinese "Kawasaki" one. the HAKKIN one is the easiest to start of all the hand warmers i have.
Note: When trying bleach, add a little HCL. I know that will slowly dissolve gold. I tried it on some placer gold. Months later, the gold precipitated as a brown powder. I think it is chlorine that is doing it. There are some high chlorine containing swimming pool powders that might be interesting to try as chlorination agents.
I'd like to understand the ph factor of platnum group metals refining
Really missing this dude, hope everything is alright on his end...
He is active on Twitter
Pd is my favorite element. Nitric parting to separate Pd from Pt is a common practice for refining, especially with finely divided PGM Black Powder, however, it's not 100% effective since PGMs seem to follow eachother in solution through the process.
Palladium is also my favorite element as it's the only element of which the number of electron shells is less than the element before it. As such it's the only period 5 element with only 4 electron shells (in its atomic configuration). Technetium is also a pretty cool element as it's very light, yet no stable isotope exists.
