Do not repeat the experiments shown in this video!
Hi everyone! In this video I am going to tell you about such a rare-earth metal as rhodium which we quite often don’t notice even when it’s right before our eyes. In the periodic table rhodium can be found in group 9 between cobalt and iridium. Moreover this element is a member of the platinum group because chemical properties of all the 6 elements belonging to it are very similar. That is why they are often found together in ores in earth’s crust. However, just like other platanoides, rhodium is very scarce making up only 0.0002 parts per million

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.

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.

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

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

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.

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

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

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)

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.

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.

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!
