Who else just stopped what they were doing and showed up to see what the hell is going on in this shed in the outback?
Nah, saw it advertised on the back of a public bathroom stall; wasn't what I expected 😢
I didn't stop, I'm still taking bong rips, now I'm just taking bong rips and watching a crazy aussie
it's about as outback as the steakhouse

This was without a doubt the least satisfying protective screen removal that I´ve ever seen
Yeah I couldn’t even get that bit right haha
@@ExtractionsAndIre At least we had a beautiful rainbow
@@ExtractionsAndIre Get it right? You employed every anti-ASMR editing trick in the book to make sure it royally sucked! We KNOW YOU! :P
I have that scale because it was like 15$ and it was about as unsatisfying.
But you have seen it.
Rhodium plating is also used in watchmaking. Specifically for hourmarkers, movement bridges and handsets. Its tarnish free and gives a very bright shimmer when polished.
Is it noticeably different than platinum you think?
@@ExtractionsAndIreits a bit brighter, but not really... Rhodium is simply used because its one of the easier elements to electroplate and has been around for a long time. Platinum plating was only introduced into the watchmaking industry when prices went insane for rhodium.
@ExtractionsAndIre IIRC fake platinum or silver jewelry is often plated with rhodium. You can tell them apart because rhodium is shinier than platinum or silver.
@@ExtractionsAndIre I'd expect it to tarnish slower, platinum loves to fade over time due to picking up scratches off of anything within a 25 meter radius. However, id also expect that to also make rhodium more difficult to polish. After looking at a fair few photos (dont have a rhodium ring to hand) i cant tell a huge difference between that and a platinum ring i have, besides the aforementioned surface scratches. Online sources say rhodium is harder than platinum, none seem to account for work hardening though.
I'M 40% RHODIUM 😎

My brother in explosions, I actually scared because I am learning something from this channel.
my deepest apologies
So while I was working in the standards division of my first job, the NIST certified rhodium standard got run over by a truck in transit. That held up every job that required rhodium because we could certify NONE of them. So that's the first thing my mind jumps to when I hear rhodium, "oh our NIST standard got run over by a truck."
Excuse me, the NIST standard got run over by a truck? That sounds like something out of a cartoon, because like, what are the odds? Also I can imagine it was more than a little frustrating.
@@laurenmp7486 Which is precisely why it sticks so firmly in my mind. When you boss comes down and says "hey we can't do any more Rhodium jobs, the NIST standard got run over by a truck," you double take. So I go talk to the QC manager, who says "Yeah, crushed box with tire marks and everything, yet they still sent it. Gonna be three months before we get a new one." My time at that company felt like a Looney Toons cartoon, but with Hydrofluric Acid, hexavalent Chromium and Methylmercury salts. I left after 9 months.
"as usual, he (cody's lab) had rhodium powder" yeah that accurately describes him
I mean, he did a full series on refining the platinum group metals from literal road dust.
if there is ONE THING cody from the youtube channel Cody's Lab is INFAMOUS for is rhodium powder. you say cody I instantly think, rhodium. even if I didnt know who he was, if i saw him at a bar i'd say "that fucker has rhodium powder, doesn't he?"

I love your channel. Especially like the sheer amount of question marks you add throughout, like fuck knows what's going to happen! But being able to wait and see what you get at the end encapsulates the entire scientific process. Keep up the good work!
Thanks mate!!
i also have no idea what's going to happen
I mentioned at the work Xmas party I was a fan of a “terrible, terrible, messy, excellent chemistry channel” and old mate immediately knew it was “explosions and fire”

TAR! TAR! TAR!
i don't know why but i read the title as tier 4 rhodium chemistry and i thought you had finally become a tier 4 chemist
It's about time he became one
After how this video goes, I’m probably getting demoted down to tier 2
You're getting demoted to physicist after this
Or worse, Biologist, yellow chemistry hell@@etelmo
i read it as time 4 rhodesian chemistry and i was very excited. my disappointment is immeasurable.
I love how you're the almost the antithesis of the typical youtuber.
hype line in that patronizing youtube presenter voice: "We're going make a RAINBOW out a rock I pulled from the ground"
but you bro: "We're turning expensive metal into sludge using drain cleaner cause it might make some cool colours"
An "insane" RAINBOW, surely?
5:46 “a scientifically interesting way to die screaming” HAS to be my favourite joke you dropped in a long time, you’ve always got bangers, but that one is right up there with “This is Australia, where clouds haven’t been invented yet”
More expensive fountain pens often use rhodium as a tipping material where the nib contacts the paper, or sometimes the entire nib is plated in it (often gold plated with rhodium)
ooh fancy
iridium is also used sometimes. many of the cheaper gold nibs tend to just use steel
They also sometimes use osmium in the pen nib alloy, because of how hard the osmium makes it. It's also part of the cost since osmium is not remotely close to cheap.
Reminds me that I have a package for you that I forgot to send.
Precious metals extracted from dirt on the side of the road sent South so they can be turned back to mud on a dirty bench.
it's anthrax, isn't it
Is it roadside recovered rhodium and platinum? 😂
Calm down with the letter bombs Cody

5:43 "It's kind of tempting, because it would be a scientifically interesting way to die screaming." LMAO
28:09 This was a funny interaction. Did all the bird chicks grow up and move out, by the way?
"scientifically interesting way to die screaming" UA-cam views would go through the roof but you wouldn't be around to enjoy the fame. Also who would upload it.
@@petermaddin5611Well clearly you would need to live stream it while it's happening. And do it on multiple sites so it's not easy for it to get memory holed from the Internet.
Of course you would also need to protect the cameras in some way. That also allows the screaming agony to be heard and seared into people's heads.
It would be an interesting science project to conquer.

Why watch the boring NileRed when we can watch this amazingly entertaining show!
I agree, but I want more energetics
3:53 From a jewellery perspective platinum is a much softer materials in comparison to rhodium but harder than most jewellery level gold. Rhodium in jewellery is primarily used to plate over white gold alloy since natural white gold looks like off milk, it’s a very yellowish white and most people find it off putting so rhodium is used to plate over it.
The plating erodes over time and needs to be redone every 5-8 years before the milky yellow colour is fully revealed. The amount actually deposited onto a plated ring is almost nothing, just enough to cover the metal in its entirety usually 0.9-1.2 microns thick.
I have a heavy chain I bought as a dumb kid I haven't worn in years that I can't bring myself to get the plating redone on. Fantastic investment younger me. Well done.
Funny white gold looks shit so we plate it so we can't tell. Whats even the point haha, just make a ring out of a metal you like
@@CAMSLAYER13 Fact: White Gold is poor man's Platinum.
My understanding is that it's also used for nicer quality silver since it's similarly bright colored but is harder and doesn't tarnish (but I'm not a jeweler nor wear jewelry).
White gold in general is silly imho, there is silver platinum and even palladium if used more often that at all white in color and of varying degrees of hardness.
Glad to see the love for the journal of chemical education. During undergrad I'd just try to hunt down the article for the particular lab report we had and half the time it'd straight up tell you the key pedagogical takeaways of the experiment
Everytime I see an extractions& video I grunt loudly and click as fast as I can.
I love how the reagents made throughout the rhodium dissolution were more colourful than the end result. Insert "Something something real rainbow was the reagents we made along the way something something."
Extracting rhodium from a stain is exactly the kind of step I've come to expect from this channel, excellent work as always
Rhodium is also used as a target in XRay tubes such as those in wavelength dispersive XRF spectrometers.
It’s used because it’s mostly impervious to the X-rays and it’s uncommon enough most people aren’t looking to analyze it.
Oh interesting, hadn’t heard of that use
It makes nearly monochromatic x rays so a simple Compton filter can remove the scatter x rays from secondary electrons hitting the glass. Also these tubes have about a gram of pure rhodium metal embedded in the copper anode.😮
@@christopherleubner6633 that too. Although I think the tube windows are usually beryllium at least it was on the model I worked with.
Wow really gave me a fun emotional rollercoaster with the sulfuric acid.
Because when I saw it I was like "oh, the rhodium dissolved quite nicely. Decent colour change"
Then I saw that the rhodium hadn't been added, and that was just the colour of the acid.
Then I thought "oh no"
"if an experiment is designed for an undergraduate to perform in under three hours, I have a reasonable chance of performing it, given unlimited time..."

@@stamasd8500 true, lol

"let's do something for the fuck of it, cuz that's what life is about", very true
"I am tempted... It would be a scientifically interesting way to die screaming"
Superb.
Thoughts:
- That graph is awesome - It SO NEATLY goes back to the trend!
- I always weigh a couple of coins (known weight and have on hand), which gives a pretty good idea of the % inaccuracy of the scales to cater for (would then instantly know if the rhodium was indeed .48g). Only useful to .01, but useful at that order of magnitude at least...
- Please do an aussie hip hop song called Glass on Glass Erodes the Flask. "I take out the bar...As usual what's left is tar".
- I love the mad scientist, dirty/broken equipment stuff on this channel more than the clinical robotic channels (which are great in their own way)
great vid as always, thanks!
Journal of Chemical Education is seriously underrated. Cool bits of chemistry which are educational and accessible. My old supervisor published a few papers in the journal and I always thought it was cool that they actually let you explain what was going on (rather than everything actually useful being banished to the SI).
They did some cool stuff with practical use for amateurs, such as digitally enhanced thin layer chromatography DE-TLC. It's the combination of regular UV-visualized TLC and a digital camera using standardized settings. You can measure the intensity of a spot with photographic software and compare to a series of known concentrations of that same product. From that an unknown concentration can be quantified. Which extends the scope of TLC from merely qualitative to quantitative as well.
@@bromisovalum8417 we were mainly phys chem, but I do recall stumbling over a reference to one of my old group's (not my own) papers on sciencemadness forums.
That rhodium price graph is basically a textbook example of the general bubble graph lol. Always a joy to see it in the wild.
best quote and perfect motto of the channel:
we tha expensive metal and turn it into sludge using drain cleaner ~ to maybe see some cool colors.
I couldn't stand chemistry in school, I hated it and yet i can't get enough of your videos! Really enjoy all of them.
You're doing a fantastic job!
I didn't hate it, but nothing ever worked (except maybe boiling some water or making indicator paper change colour with acid) so had no interest in studying it further.
See you just needed it taught by a doctor of physics.
It’s because chemistry isn’t the issue you had, it was the school
@@CatgirlExplise6039it was definitely the chemistry itself for me. Every single rule has 10 exceptions to the rule and that's a no-go for me. "This reaction works like this always sometimes maybe 70% of the time 100% of the time".
"Glass on glass and erode the flask"
Pure pottery.
man if thats a rainbow then the various colours of aged piss bottles down the back of my bed must be an exhibition worthy painting
Solid! I think it's safe to say the real Rhodium Rainbow was the Cubanes we tarred along the way? Nah, the real Rhodium Rainbow was clearly the Ligands we tarred along the way
Spray your deteriorating paper labels with a rattle can coat of clear acrylic and they won't get worse. Won't get better either, but it will stop.

Rhodium is also used in catalytic gauzes for nitric acid production. (Interestingly, actively creating NOx rather than destroying it such as in a catalytic converter)
Rhodium is used almost exclusively in gasoline vehicles (essentially all catalytic converters - three way catalysts - include Rhodium), not diesel vehicles. The one caveat is that there are some Diesel Oxidation Catalysts that included rhodium, but most are Platinum and Palladium based. Therefore, any decrease in Rhodium price attributed to demand is likely linked to declining demand in gasoline vehicles, not diesel.
I remember friend that fly transport plane was somewhere near Botswana border in S. Africa when he stuck for few days due to covid told me that not a single mine stopped back then(and he met lots of truckers that drive in-out of mines), so aluminium hat people can add that to their conspiracy theories as they bumped prices for rare metals but not because mines stopped :D
Rhodium price swings are based on the Catalytic converter market. Since nearly all PGMs do the same job, manufacturers buy the cheapest PGM for converters. If Rhodium is cheap, they buy that, which causes the price to rise, meaning other PGMs like platinum become more available and they buy that. PGMs swing from the cheapest, and since supplies are constrained, they swing wildly based on this market effect. You are welcome sir.
Jeweler here. I think it’s brighter than platinum. It’s used to plate silver and yellow gold fairly often.
I've never wasted so much time in my life as what follows me standing in in lab and saying "I'm just going to do it all in one step"
my wife is very allergic to metals that oxidize (silver/copper/nickel/etc...) even at 14k gold. I had her 14k wedding ring Rhodium coated for $40 USD and there's no allergy issues, and you honestly can't even tell. it lasts around 4-6 months depending on how often she wears it but we only can tell the rhodium plating is worn off when she starts to have an allergic reaction.
With acetic acid, this is technically rhodium pickles.
that's one of the sentences ever typed
14:08 The forbidden lemonade
I really appreciate the amount of work that goes into these long videos, not just in the shed, but in the editing. Not many channels will put that kind of effort just to make the full yellow chemistry rainbow, keep it up.
idk why but i always see your vids right after upload and it always makes me jump out of joy.
favorite australian, (fake chemist), physicist, madman and kangaroo fighter
if i die screaming, all i can hope is that it's scientifically interesting
"One thing we do have is enthusiasm." Reasons this is one of my favorite chem channels. The sheer "fuck around to find out" energy hits way different than the precise by the book vids.
it’s really strangely gratifying to hear someone call a subject i understand moderately well “pretty advanced stuff”! loved inorganic chem, can’t wait to do more of it
19:48 ethanol is less dense than water but it is actually more viscous (but not by much)
Ok good to know!! I should’ve checked before I start saying stuff like that
"a scientifically interesting way to die screaming"
at the end, when you added the chemicals and there was immediate and visible color change, I said "WOW" out loud. It may be "garbage shed chemistry" but it's still incredibly cool to see the effects of crazy quantum interactions at a macro scale.
Absolutely love this. Those colours look exactly like the rainbows you get in Mount Isa with all the contaminants in the air - oxides of sulphur and lead, volatile organics, unidentified dirt particulates - so pretty much exactly what you did here. Success!!!

A very similar experiment can be carried out by redox titration of vanadium.
Similar skill level and time requirement bur WAY cheaper then Rhoduim.
Maybe as a pitch for the next video for a comperison
Too bad Vanadium is really toxic.
@@richardblair3021 so is Rhodium and Osmium and Iridium and most other heavy metals. Does it stop Tom? Guess not
True, one should limit exposure to heavy metals. Osmium main hazard is from its oxide which is volatile and unstable - osmium plating the eyes. Rhodium oxides are insoluble, although the chloride is exceptionally toxic toward plants. Vanadium oxides are water soluble, persistent environmental hazards and pretty much bad news for anything exposed to them.@@emmanueleferrarotto2986

I really enjoy watching your content. You make chemistry fun, Thank you for putting in the hard work making these videos for us to enjoy.
Your channel is the epitome of what UA-cam originally strived to be.
What's the _DEAL_ with phosphorous pentoxide? It's so expenssssive
Most fountain pens over £100 or so usually have rhodium plating on the nibs. A good example is the Lamy 2000 which has a gold nib allowing for a bit of flex and a smoother writing experience with rhodium plating to stop the nib from tarnishing as easily (and to fit with the overall aesthetic)
You know an awful lot about pens don’t you?

Your channel is one of those where, even if I don't know everything you're talking about (not a big expert in any sense of the word in any department) the chaos and cadence alone makes these videos some of my favorite to watch.
