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!

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

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.

Another great video! Thanks Thoisoi!

Love the hand-warmer information!

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

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

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

Once again, thank you for the great video.

Another great video. Thanks, Thoisoi!

as always, great video, thank you

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

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

Спасибо! Great video!

I love the way you say “Iridium”

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''*

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

Very good video and answered all my questions

So glad that this video is narrated by you, ❤

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

Nicely put and good way to understand keep videos going

Another cool video. Keep up The Great work

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..."

Thanks for the information

great vid as always

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

This was a good one. Good job!

Always educational, thank you.

Just gained a new subscriber 😊

This is one of y all time favourite channels 👍🏻

Awsome footage 👌

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)

Great explanation

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

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.

Great work

Thanxx for buying such an expensive metal for us

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

Thank you for the information.

Very interesting thankyou for sharing

great video!

你是我所知道的KZfaqrs之中，最用心的化學KZfaqr

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

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.

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.

Love the videos.

You really know your stuff about metals.

Please do a video on fluorine.

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

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

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.

I REALLY love how he says "gas burner"

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.

awesome!

I love catalytic reactions.

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

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

friend which product should I use to PRECIPITATE rhodium

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

Russia is the second largest producer of rhodium in the world (behind South Africa). Russia is also the second largest producer of platinum and gold. And Russia is the LARGEST producer of palladium and the fourth largest producer of silver. No other country in the world is in the top 5 of all of those five metals, except Russia.

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

Exciting times 🎉

Bravo !

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

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.

What was the first background song playing in the video?

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!

Nice when you have the lab set up, funds, and most importantly the knowledge. Filming reactions is not easy. The risks, exposure, and effort would intimidate all but the most dedicated. This is not a university supported thing here. Some people just like sharing knowledge, exposing hungry minds to the real world of science. Compare these videos to the religitard ramblings and assertions coming from a money grubbing minister making threats to those who don't send him money. Большое спасибо!

what an amazing metal, impressive

Good video.

I love the way he says "jehrls".

Verrrry gooood

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

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

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

I like the look of the black sulfide coating of silver

Why, in description, you have written Palladium?

excellent

What song plays at the end of your video?

What would you use rhodium for?

Nice vid

What is song in background? It is very nice

Could you make a video on cobalt 60

Title: Rhodium - The Most INVISIBLE Metal on Earth! 0:18 seconds in the video:

Love the gta footage

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

Video: [Russian Accent] Me: "Okay... I'm listening. You have my full attention."

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

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

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

Can you please do iodine next?

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

Thanks bro i am always a big fan of you and i always loves rassians thay are good

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

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

You sounda like Borat. You from Khazastan? Very nice!

How can find out its oer ?
