At 0:56 there is a mistake in the video. Cesium Peroxide is Cs2O2. Sorry for that! In this video, I tried to show more of my thought process and the procedure itself. Let me know if you like it or if it is too lengthy and gets boring.
I think the general amount of information was great, it could be a bit tighter but i think that mostly comes with more routine and experience. Which is great, because that means we get more videos ☺️👍
I liked it just the way it was. Especially because you didn't sanitize the video by editing out the cracked vessel or just starting it over. Quite enjoyable, thanks for sharing
Additionally, cesium monoxide's formula is Cs₂O, not CsO. Cesium peroxide is Cs₂O₂, as you know, but it's also possible to make other cesium oxides, and you probably did, at least a little bit. At least three cesium suboxides are known, Cs₇O, Cs₄O, and Cs₁₁O₃, although I couldn't find specific names for them, and then there's the oxide between cesium peroxide and cesium superoxide: cesium sesquioxide (Cs₂O₃).
This channel is becoming my one stop shop for all things Cesium, a most fascinating element. Great video, keep up the great work! Also oof, that moment when you cracked it. Painful but glad you persevered.
What an exercise in frustration and self hatred lol, I love how you beat yourself up over this stuff and get pissed off, the realness is much appreciated!
Awww! I felt so bad when you said you cracked ghe reaction vessel 😲 what a shit! I admire your dedication and perseverance to this experiment 👏👏👏 new sub just for that alone 😂
"Sit on a couch for approximately 1h hating yourself for what you had done" I don't have the proper equipment to replicate your entire procedure, but that one step I can do.
ein thema ist mit dem Ofen und dem Bor-Silikatglas: Bei den hohen Temperaturen neigt das etwas zum "altern" und kriegt unter umständen mikrorisse. Deswegen werden Cerankochfelder eben nicht aus dem Bor-silikatglas gemacht. Quarzglas ist diesbezüglich gutmütiger. Ansonsten: Trotzdem mega geiles fortgeschrittenes Gebastel!
A good way to make alkali oxides peroxides and superixides (oh my) is to heat the alkali metal to bpiling and react the vapors with oxygen in a burner. The oxide is Cs2O, the peroxide is Cs2O2, and the superoxide is Cs2O4. The last demo was pretty neat. 🤓
Nope. superoxide is CsO2, no doubling of the stochiometry needed. For Cs2O2 (instead of CsO) however, you are correct because the (O2)2- anion is diatomic.
K02, there's something I haven't played with in 35 years... some neat stuff. Interesting to me that the cesium superoxide is almost identical in appearance to the KO2.
Your attention to practical detail is thorough, and fascinating to watch for these rarely videoed processes. However at 0:56 your formulae are incorrect. Cesium (mon)oxide is Cs2O and cesium peroxide is Cs2O2. Non-chemists may get confused.
Really cool. Great job That long....not being sure if it was going to work, would have driven me crazy. I bet you were missing a glove box. I made a pyrophoric cmpd that fell out of solution and I filtered the solid straight out of the reaction flask on a schlenk line , rinsed the solid still on the line and still attached to the reaction flask. Had to take everything to the glove box to get the solid, though. But it was made, cleaned, and the solvent removed all on the line without taking anything apart.
I think its interesting that with potassium there are these horror stories of people pushing some oxidized crust into it and it exploding but with partially oxidized cesium which should be a more non forgiving mixture of highly reactive metal and superoxide nothing much is happening. Of course I am happy nothing happened to you during the procedure but it seems curious why potassium seems to be more reactive in these situations if the reports are indeed correct.
Im new here but really awesome dedication to the experiment. Very interesting and informative. I totally appreciate your content and am excited to take a look at your library.
I think the magnet you use has a yoke, which makes the field very short range, compared to a separate magnet. That is important because you do not touch the paramagnetic substance.
@@AdvancedTinkering Wow there's simply no doubt in your preparation ! When you brought up the scale I immediately thought about the magnet itself reacting with metal in the scale mechanism and then second later you brought up the foam :D Now seeing the super pure grade argon, great stuff.
I was thinking about that for quite some time now. But rubidium chloride is pretty expensive and I currently do not have the money for it. But as soon as I get some rubidium chloride I will make a video :)
The problem is, that the price is due to the rubidium. The tartrate is even more expensive. But by now I allready made a video about the isolation of rubidium from rubidium chloride.
Easier said than done. How would you purify/separate a mixture of different (moisture sensitive) oxides, hydroxide and unknown impurities from inside the oven?
@@AdvancedTinkering if you spilled the whole thing it would be impure anyways, so how pure do you think this amount was? I'd try to dry it and bring it all to a known oxidation level. But for removing the unknown material it gets really tricky and is probably not worth a huge amount of effort. Did you use it for anything yet?
When the glass broke I immediately blanketed it with dry argon and collected everything that did not come into contact with the oven. Due to the high temperature I think most of the product was protected from moisture. But it definitely did decrease the purity. Yes, I used the superoxide to make cesium ozonide.
I would have expected the magnet to move the particles inside the tube but I didn’t see any internal movement, did it move lol, if not, I’m curious why not?
Hypothetically, could you attach a glass rod to the side of the reaction vessel and hold the glass rod, instead of clamping onto the outside of the vessel?
Cause it would show a negative reading regardless it position to the vial cause it would always be pulling up the steel and he did show that he placed the agent far enough away hence the foam block and proof showing magnet not interfering with scale
You need to repeat the measurement with a piece of the same glass you used to make the tube. How do you know the attraction is not due to something in the glass, or contamination of either the sample or on the outside of the glass? The tiniest amount of ferromagnetic material would do this!
I actually tested it with the glass and did not observe any effect. But you are right, it could be caused by contaminations of the sample. I could decompose it to the oxide again and try again. If it was caused by a contamination, the effect should still be visible. If not, it should be gone. It is well known, that the superoxide ion has paramagnetic properties. But it would be interesting to try nevertheless.
Two main reasons: I got my hands on a lot of lithium for very little money. Which means buying calcium would be more expensive for me. And I have tried it once with calcium and my yield was far lower than when I used lithium. At some point I want to revisit different reducing agents including calcium.
I wonder what would happen if you suspended the Superoxide in water. Would you make a sort of paint (which would presumably turn black again eventually - I don't really know the full chemistry here I'm just a nerd) or would it do some crazy reaction? Probably best to use a fume hood in case it makes something dangerous. But water is one of those substances that almost always does something interesting or "interesting" to the other chemical.
Nice idea, it would make an appealing paint colour - but no it would fizz violently and might even explode. Superoxides have "too much" oxygen in them and lots of things can cause that extra oxygen to be released as a gas, of which the addition of water is one.
(1) 0:40 Lithium is the least reactive of the alkali metals while caesium is the most reactive. Why would lithium replace caesium from CsCl . . . how is this even possible? (2) Cs2O is just normal caesium oxide, not peroxide.
Because they are two different things. In dioxide, two separate oxygen atoms are present with an oxidation number of -2. In peroxides, two connected oxygen atoms with an oxidation number of -1 (each) are present (O2^2-). In superoxides/hyperoxides, the oxygen atoms are also connected but have an oxidation number of -1/2 (each) (O2^-).
Lithium actually has a slightly lower redox potential. But it would also work with sodium. The reason it works is that I am constantly removing Cs from the reaction mixture and thus shifting the equilibrium to the right side of the equation. I explained it in more detail in my first video about the cesium isolation.
That’s a dumb question. You have to study it for it to be a hobby for one and for two when they’re practicing chemistry they obviously are studying it. Are you asking if it’s their profession. Yes, because they’re being paid to perform chemistry… Your question is answered simply by this video existing

Was watching an old nilered video, heard the term “super-oxide”, and here I am- 👍

Excellent work there.
What's the purity of your argon?
Thank you. I am using Argon 5.0. So it is 99,999%.
@@AdvancedTinkering Wow there's simply no doubt in your preparation ! When you brought up the scale I immediately thought about the magnet itself reacting with metal in the scale mechanism and then second later you brought up the foam :D Now seeing the super pure grade argon, great stuff.
Oh so gutget for you when you broke it :'( But you did good man! Push on through!
Would a tiny stir bar in the cesium be feasible. I know I have a couple that are the size of a tic tac candy.
It may help a little. But I don't think it would help a lot. And the sir bar would have to be a glass one. If it's PTFE you might have a bad day.
Any chance you have or could make some rubidium and then show its alloys with cesium and other alkali metals?
I was thinking about that for quite some time now. But rubidium chloride is pretty expensive and I currently do not have the money for it.
But as soon as I get some rubidium chloride I will make a video :)

You're shaking the cesium oxygen mixture!
That's scary AF, because it could've just oxidized the surface layer.
This puts extra yum inside.
Good video nice production

"I have lost more than half of the product"

It's not gone, it's still there... You could just purify it

Super! Thank you very much!
06:40 My first thought: the oxigen needs bubbler to be introduced from the bottom up.
Pure Cesium, very reactive... It could Kbum it!...
Hold up... It's yellow...
But it's inorganic, so it's fine. Only yellow organic chemistry is bad :D
@@AdvancedTinkering xD nice. Thanks for the info.. I forgot that yellow is bad only in organic chemistry :D
@@AdvancedTinkering I don't know if Tom would agree with you on that.
I would have expected the magnet to move the particles inside the tube but I didn’t see any internal movement, did it move lol, if not, I’m curious why not?
If you positioned the reaction tube horizontally….I think a more complete oxidation would occur…..may have to chill
One year later you can now find pictures on the internet lol
So, now, there's an image of it in the internet - or is there?
You might be the first person to *drill* cesium.
Hypothetically, could you attach a glass rod to the side of the reaction vessel and hold the glass rod, instead of clamping onto the outside of the vessel?
how do we know that the magnet isn't just pulling on the steel plate of the scale?
nvm the boat thing convinces me
And I have tested it without the vial(you can see it in the video). The scale did not react to the magnet if the vial was not present.
Cause it would show a negative reading regardless it position to the vial cause it would always be pulling up the steel and he did show that he placed the agent far enough away hence the foam block and proof showing magnet not interfering with scale
a question please, Cs is more reactive than Li, how come Li can rob it of its oxygen?
you is from Spain!
Suppose that your oven made of paramagnetic material. Could it be the parts of the oven that interacting with a magnet?
would like to see a Diffractogram of that powder

Why don't you reduce with calcium metal? Much cheaper than lithium.

I just figured out that if you have one carbon and 2 sulfur you have just made CS2
How stable is this stuff?
Under inert gas it is stable. But when exposed to air it reacts with the moisture to form cesium hydroxide, oxygen and hydrogen peroxide.
Does cesium chloride taste as bad as Explosions&Fire says it does?
The peroxide formula at 0:55 is wrong. That's the oxide. And THIS is even harder to obtain...

But why "superoxide"? Isn't 2 oxygens a dioxicide normally?
Not too. lengthy, but I wonder if mixing A stream of Cs vapor with oxygen wouldn't be faster & simple r. Hopefully not too much faster.
Why isn't it called cesium dioxide
Because "superoxide" tells you there is a O2- anion. Dioxide only refers to two oxygen atoms.
@@AdvancedTinkering does that mean it's structure is like C's - O - O. ?

Lithium is the least reactive of the alkali metals while caesium is the most reactive.
Why would lithium replace caesium from CsCl . . . how is this even possible?
(2)
Cs2O is just normal caesium oxide, not peroxide.
0:58 WRONG! CsO or rather Cs2O2 is called cesium peroxide. And Cs2O is the cesium monoxide or rather just cesium oxide.
You are right. I must have missed that when editing.

Why Lithium reduces Cs+ into Cs? Should be the opposite...
