Rhodium - The Most INVISIBLE Metal on Earth! 

Ex-jeweller here. Just a small correction on the information regarding rhodium plating for anyone that is interested. We almost never rhodium plate silver (the only time we do, is when specifically asked to by the customer, and they are charged accordingly too) as it would make the pieces prohibitively expensive for the value of the metal. We pretty much exclusively use rhodium plating on white gold alloys to help keep it's lustre, as 14ct w/g alloys and above have a very grey appearance, even when polished. Also, replating a piece is so expensive because we have to remove EVERY trace of rhodium, smoothe and polish the piece, isolate where plating is needed, and then plating it in $1,000(aud)/Lt solution. If any bit of rhodium was missed in the initial removal process, it will cause a cloudy bloom on the piece, and you need to start all over again from step one. And if your solution becomes contaminated in any way...you have to buy a new bottle, as it will just cause flawed platings otherwise.

Rhodium is also used to coat "White Gold" a mixture of pure gold and white metals such as nickel, silver and palladium. It adds to the shiny luster and reduces tendency to scratch.

Learnt more about rhodium than from any book. Great work, love your videos!

Amazing. Rhodium has tripled in less than 5 years and is recently increasing ~1% per day, and there are still only two videos on youtube dedicated to it that are less than 3 years old. If you are reading this, you are looking at one of those rare 10 bagger opportunities that everyone will talk about in hindsight.

Plating Rh on silver, defeats the disinfecting properties of the silver

Love your tuxedo cat. He's a twin of my own.

I've learned more from your channel than 4 years of college chemistry!!! Thank you 🙏

Another great video! Thanks Thoisoi!

2:40, also seen as the deadly stuff right at the beggining of Prometheus.

Спасибо! Great video!

as always, great video, thank you

Once again, thank you for the great video.

Your videos are the best. Thank you for making all of us a little bit smarter.

0:06 - Hello heroin! Dude, I understand you...

Love the hand-warmer information!

Another great video. Thanks, Thoisoi!

You are great....lot of information we will learnt Please make an video on COPPER +ALUMINUM +IRON ALLOY

2:12 - 2:16 *''forging metal which is two times as expensive as gold is not a big deal''*

How rare it is they sure do use it in a lot of stuff

That was quite informative, thanks for sharing. We overlook a lot of things in our daily lives without realizing their importance.

I love the way you say “Iridium”

Great content mate, cheers! Honestly I learnt more about elements from you than from my whole school life. When I see your recent ones, I noticed one thing better than old ones. Finally you're using tripods. Appreciate it mate! No more pointless shaky videos. Can't wait for your new vids. If I may have a request, I'd love to see you making videos about latest found elements if possible (113-118)

Another cool video. Keep up The Great work

great vid as always

Nobody: Rhodioum: *I'm the invisible metal*

Thank you for your presentation. Should have had you as a professor in my physical sciences classes!

For the hand warmer, the Rh catalyst, along with the other catalytic materia, reacts with the vapor of the fuel. So instead of buring in a flame, it merely reacts with the catalyst to produce minor combustion. Like a catalytic converter where the co1 passes over the catalyst and it's transformed unto c02 as an oxigen is added to the carbon. Much like reacting hydrogen with platinum.

This was a good one. Good job!

I was in the Swarovski store with my girlfriend looking at a pendant with a rhodium flash. My girlfriend asked the clerk what rhodium was and I will never forget her explanation: "Rhodium is like, an element, from like, the periodic table of the elements..."

Just gained a new subscriber 😊

Always educational, thank you.

So glad that this video is narrated by you, ❤

Nicely put and good way to understand keep videos going

Thank you for the information.

In the 60s I won 1st place in 5th grade science fair. I got a lapel pin of solid Rhodium for prize. I knew it was special but eventually misplaced it. Damn! Wish I still had it! Edit: I just remembered I won it as a 5th grader against all the grades thru 10th. That's why the prize was so good.

4:10 Rhodon (ρόδον) in Greek means rose not pink. This metal has this name because its salts have colors like red or pink roses. But other than this small mistake video is great.

thank u for ur time andservice to instrukt followers with good info

Great work

great video!

thats why its my favourite element! many applications, especially catalytic, but not many people know about it.

Very good video and answered all my questions

你是我所知道的RU-vidrs之中，最用心的化學RU-vidr

Thanks for the information

Love the videos.

If this was melted & then moulded would it be good for small jewelry like a ring?

Awsome footage 👌

Please do a video on fluorine.

Very interesting thankyou for sharing

Great explanation

Aa a jeweler, I can say that most sterling silver jewelry isnt coated with Rh, unless it's hallmarked as such or during the creation of agentium silver (has other names in industry) which gives it a higher resistance to corrosion. I'm not sure of the hallmark laws in Russia, but in the US silver has to be hallmarked if It's made of other metals. Such as sterling hallmark (92.5). Rh is typically mixed with gold to make white gold and is hallmarked as such. Love your videos, just wanted to put that out there as a friendly heads up.

Thanks for this very interesting video! Looking forward to your next one :)

It´s February 2020 now and Rhodium is 6.5 as expensive as Gold. - 9,500 EUR per ounce vs. 1,430 EUR P.S.: Thanks for your great videos on all the elements. You're really filling a gap.

This is one of y all time favourite channels 👍🏻

Thanxx for buying such an expensive metal for us

I love silver juwerrly, and I love sunny days when it’s 25 Celsius Degrees. Plate in em juwerrly is nice too

I watch for the chemistry, and stick around for the cat cameos at the end.

I REALLY love how he says "gas burner"

What was the first background song playing in the video?

i almost closed the video before it ended, glad i didnt :)

Another use of rhodium is in catalysts made out of rhodium coordination complexes, used to manufacture high-purity acetic acid from methanol and carbon monoxide

You rightly remember that silver metal blackens over time by forming sulfur derivatives. The zinc metal reacted with silver sulphide, and the cooks of the old days put the blackened ladles, forks, knives and spoons on a gutter plate and plunged them into the tap. I did it again yesterday and in less than one night the silver metal had found its complexion as a young girl! And as this regenerated electrolytic metal is free of impurities favoring chemical attack, cutlery stays clean for a long time!

I love catalytic reactions.

awesome!

I am working with ore. I have had numerous problems trying to melt. I finally got them to melt and decided to put the hard buttons in nitric/water hot to remove any junk metals, copper, iron. I am ok with the nitric/water dissolving my ilver and palladium also. I went to go flatten the buttons before putting in nitric/water and they was very hard but broke into pieces. Now I have a white substance in the bottom from the buttons. I had took a button the other day and put it in AR and got a white in the bottom also. figured it was silver, but now that I have the same looking white in the bottom of nitric/water soak I dont know. As I said all kinds of problems melting to a button. Finally a guy said use a Arc welder with carbon rods, this worked but now I have this white. Normal forge is not hot enough to melt. I dont know what it is. Any idea's?

Very infomative but I cant stop cracking up because this dude sounds exaclty like Borat.

what an amazing metal, impressive

What would looks like that the ruthenium, rhenium, osmium, iridium metal pellets hit by a hammer? How brittle are they compared to rhodium?

Explain why iron is the most stable element you are the best of explaining the elements

I was 17 in 2003 and I just wished I could learn as much in school back then like I am learning right now.. might have influenced me more to be a chemist.

You really know your stuff about metals.

Nice vid

Why, in description, you have written Palladium?

Bravo !

the Argentium silver alloy is also really interesting, doesn't tarnish at all.

It looked like the rhodium got red hot while being hammered

may I ask, what chemicals do I dissolve to dissolve metal Rhodium? Thank you!

I've been walking around with freezing hands all these years, not knowing about these incredible catalytic hand warmers!? :o

Good video.

I love this metal its so rare makes it special. My second favourt platinuminumoid

I love the way he says "jehrls".

Is that true that rhodium is the only element that forms Rh(quad bond)Rh? And the 4 the bond is called Delta bond? And that blob of Rh is it in it's elemental state or like a metal lattice? Help anyways, gud video dude

7:48 🤣🤣 you have to listen to this, it coud be a poem

What song plays at the end of your video?

Sir please make a video on Oganesson (Og) the last element of our periodic table .

What is song in background? It is very nice

friend which product should I use to PRECIPITATE rhodium

I like the look of the black sulfide coating of silver

When I have enough money one day I’m going to design a cabinet with the exact shape of the periodic table and make it able to add new sections for new elements in the future, I’m going to try get a sample of every element in legally allowed to own. That’s my goal

there are some issues with the english subtitles (7:00 and beyond)

By adding a nuetron in uranium 235 it will release krypton , barium , 3 nuetrons and heat What if we react krypton , barium and 2 nuetrons. Will it become uranium 235?

You missed one important use of rhodium: it is used (together with other platinoids) to make dies for the production of glass fibres, such as those used in fiberglass, rock wool and optical fibres. The hardness even at high temperatures and chemical inertia of platinoids are what makes them ideal - if very expensive - for this purpose.

Exciting times 🎉

Love the gta footage

Did not know rhodium was this rare thus discovered on earth what can do that platinum cannot. Too brittle naturally coats silver? or added? and palladium as platinum already do this catalytic converters, too rare to make sense for uses that we can already get through the other 5 platinum group elements. I would like to see (learn) what it is doing or not compared at the same time as the other 5 elements. Thank you, you and this channel make me learn/think and that is not an easy task. Lance & Patrick.

excellent

How can find out its oer ?

Could you make a video on cobalt 60

I saw a "Mission Impossible" episode back in the '60s where the plot was smuggling Platinum in shape and quantity of AUTO FENDERS! IM team "discovered" the plot by pointing out to a border guard that the 'fender' bent as easily as 'butter'...

Ur voice irirtated me in whole video.. Btw nice information about rhodium.. 👍

Nice
