Distilling Highly Reactive Potassium for a Dangerous and Unique Gift

[@That_Chemist]

I once visited an old decommissioned highschool chemistry lab (and when I say decommissioned, I mean they left all the chemicals and decommissioning didn't happen at all), and they still had a massive jar with more potassium than I have seen in my entire life - they had an ampule of mercury roughly the same size as the one you made in this video, but the mercury had mercury salt crystals floating in it 🙃

[@dianeramakers3368]

Very impressed about your glass work. And very surprised that it’s not allowed in Germany for a private person to own nitric acid.

[@darylcheshire1618]

I’m surprised too, in the ‘70s in Australia, it was possible to buy conc sulphuric acid and nitric acid. The drug labs and the ban on precursor chemicals have spoilt it for everyone.

[@kapytanhook]

Only the ban spoiled it. I don't mind that some people enjoy drugs

[@KallePihlajasaari]

A common reason for people to contemplate prescription and banned pharmaceuticals is when they want to self medicate due to failure of the medical system to address their PTSD, pain, depression, fear and all those other things that the system provides. Alcohol has so many negative side effects that if is not a innocent alternative. I believe everyone should have the right to make AND prescribe for themselves ANY compound if it does not endanger others training on safe procedure and therapy to understand the potential addiction, child welfare and antisocial costs they may cause and agree to accept in advance. I do not support sale of drugs without someone taking responsibility and I think the medical industry has dropped the ball on many occasions. The second class of chemicals that I feel have been targeted mostly unfairly are those that enable the citizen rabble to rise up against corrupt and totalitarian governments. I long for the day that governments have a a primary goal the general wellbeing of every citizen and not industry lobby groups. This near total failure in the social contract drives people to desperation because they no longer (if the ever did) have a voice. Even in multiparty states the financial interests usually cross all party lines and any change is always to the detriment of the common citizen and for the benefit of the billionaire class. There is a strong correlation between disarming a population or a segment of the population and a subsequent genocide, strong enough for an honest politician to PROMOTE a well armed militia but usually any means of opposition is rather removed and means to exert force are only held by the police.

[@MichaelLapore-lk9jz]

Germany is in the process of stupidity on a massive scale, by shutting down all their nuclear reactors! So all of Germany's citizens pay out of their ass for electricity!!!!😅😂

[@davidfranco7480]

Same in France, for the better.

[@robertlapointe4093]

Nicely done. Back when I was doing this sort of stuff in grad school, we routinely washed our glassware with acetone to remove bulk organics, distilled water to remove the acetone, an overnight soak in chromic acid (~ 90 g of Na2Cr2O7 in a liter of concentrated sulfuric acid) followed by 3X rinses with tap water, concentrated ammonia, tap water again and then distilled water followed by drying at 200C under high vacuum (~ 10-4 mbar). The folks in the lab next door (Klaus Theopold's group) used piranha solution (50/50 mix of concentrated sulfuric acid and 30% H2O2), instead of chromic acid until a post doc nearly killed herself when she dumped a batch of fresh (hot) piranha into a flask of acetone by mistake (we felt the floor jump next door and were deaf for a while). If Germany has a problem with nitric acid I imagine it won't be happy with either of these methods. The main point is to oxidize any residual organics or metals (which can then be washed out). Another method, which I used in an industrial setting, was to run the container (either glass or stainless steel) through an annealing oven at about 550C, which would burn off any organics (usually polymers in my case) followed by a blast of compressed air to remove any ash.

[@felixr1785]

In professional settings and universities nitric and sulfuric acid are commonly used, but they are banned from free market sale to unlicensed individuals in all of europe due to anti terrorism laws, just as finely powdered aluminum

[@AdvancedTinkering]

Since the still was annealed at around 550 °C all the organics are probably gone. But maybe some inorganic impuritys were still left inside the ampoule.

[@treelineresearch3387]

The way the metal flows upwards in rivulets from the distillation flask is really uncanny, I thought the footage was reversed at first.

[@AdvancedTinkering]

It does look unreal. So far I have only seen this with cesium and potassium.

[@bladdnun3016]

I'm inclined to think it doesn't flow so much as it evaporates and immediately condenses slightly higher up.

[@BESHYSBEES]

[@KallePihlajasaari]

I think it is driven up with the flow of vapour that condenses further along. Same way that a diffusion pump will give up momentum to the gas against a pressure gradient here the potassium vapour diffusion pump is trying to move the condensed potassium against gravity.

[@elitearbor]

What a fascinating video of such a basic process. I doubt I've ever seen, in person, that much potassium in one place.

Can you imagine being on a planet that has liquid Potassium condensing into a metallic rain? The drops would fall from the sky like soft puffy bullets. Oxygen would not be anyone's friend in such a place. The sight of those vapours condensing in the glassware is the sort of thing that drew me to Chemistry in the first place.

[@-r-495]

„cooking with friends“… happy to see you too up to it ☺️

[@manatoa1]

That distillation was remarkably beautiful. I loved the look of the potassium in the ampoule before you remelted it. The voids made it more beautiful somehow.

[@AdvancedTinkering]

Thank you! Yes, remelting it was a mistake. It looked a lot better before. Won't do that next time.

[@iseriver3982]

Purifying potassium seems like a rather complicated way to simulate lava tubes, but it's very pretty.

[@ChemicalForce]

Great video! As I noticed many people like to watch alkali metals being cut. I think a video called “I cut potassium for an hour” will get a lot of views. 😄 Now I'm trying to make a video about the Soviet alloy (potassium cesium and sodium alloy - the most fusible alloy in the world), and I mixed liquid potassium and liquid cesium, but it's a pity I don't currently have access to suitable equipment to do this in an inert atmosphere, and not under a layer of mineral oil or kerosene 🥲🥲🥲

[@brfisher1123]

I like watching the alkali metals below sodium being melted under an inert atmosphere as they all look absolutely gorgeous especially cesium!

[@AdvancedTinkering]

Thank you very much! I think cutting potassium metal in a glovebox so that the surface stays shiny would be a very nice video :D Elias and I actually made the CsNaK alloy in an older video. But only under mineral oil. I also thought about making an ampoule of CsNaK by distilling all three metals into one ampoule but haven't had time yet. And apart from the low melting point, the alloy doesn't have any interesting properties, does it?

[@brfisher1123]

​@@AdvancedTinkering It must be an honor to have Chemical Force comment on one of your videos considering that like you he also puts out some pretty great content, I envy you!

[@pelegsap]

It was just a question of time until a chemistry youtuber would set up a Schlenk system... pretty awesome, and you definitely deserve it. You can't imagine how envy I am 🙂 (Außerdem, wenn ich das englische Wort "gift" im Rahmen von Chemie sehe, ich lache immer... 😛)

[@toresbe]

Fun fact: Das deutsche Wort hat denselben Ursprung. Gift im Sinne von "giftig" stammt von der Verwendung dieses Wortes als Euphemismus, ähnlich wie man heute "he was dosed" sagt. Es bedeutet im Kern "etwas, das gegeben wird". In diesem Sinne bedeute das Wort auch im Skandinavien zusätzlich "geheiratet", im Sinne von "zur Ehe gegeben". Ich erinnere mich noch an den Aha-Moment als Kind, als ich diese Entdeckung machte.

[@brfisher1123]

I'd imagine that the potassium would've came out much better if you would've gone for another distillation round and BTW potassium is by far one of my favorite alkali metals along with rubidium and cesium due to its gorgeous shiny appearance and its low melting point like the other two plus it's a common source of radioactivity! 👍👍 I'd love to see if you can make a potassium sample so pure that it doesn't stick to the glass at all just like you did with the cesium sample a while back!

[@AdvancedTinkering]

You can believe me when I tell you that I will definitely make a second attempt at making a perfect ampoule ;)

[@Palmit_]

Beautiful. The colours and the fluidity is really engaging. Thanks for sharing :)

[@Muonium1]

Do you have any interest in the wasserhammer physics demonstration novelty? It is a simple glass tube partially filled with water, evacuated, and sealed off at the top. When shaken gently a slug of water forms a cavitation bubble at the bottom, and when the movement is halted or the direction of shaking is reversed the bubble collapses symmetrically producing a tremendous energy focusing factor and producing a loud ping or crack noise. Some channels on here such a Lutz Neumann have made them but they remain a rare oddity. There are several papers showing ~10^9 high energy (blue-UV) photons are emitted per bubble collapse event and I've long wondered if for instance adding fluorescein to the water would allow one to visualize the flashes more easily.

[@AdvancedTinkering]

If I find the time, I'll be happy to try it out. I have actually observed the water hammer effect in my caesium ampoule. If you tilt it too quickly while the metal is liquid, you hear a pinging sound. Very worrying and a reason why I now only move the ampoule very carefully.

[@CharsimaHD]

Quick tip on scraping those per/superoxides… find yourself a bronze alloy knife. CS Unitec makes some beryllium bronze knives that are fairly hard, intrinsically safe and mostly non-magnetic. You never can tell how deep those oxide layers are. As a hazmat chemist, I’ve encountered a few “dry” pockets on the surfaces of alkali’s, and trust me, you do not want to experience that chain reaction occurring with a 500g chunk of alkali metal in your hand.

[@jannooosthuizen6588]

I was a little surprised to hear that a private citizen in Germany isn't allowed to own nitric acid. It seems vital that a private citizen would have access to various nitrates, so how could anyone be prevented from synthesizing their own?

[@nab-v1w]

hey, if you cant use nitric acid, you can do a plasma treatment 2 minutes of the glass, if possible under vaccum, it makes the glass unsticky exept to gallium for around 5 minutes before air untreat it. On other way is to heat the glass at 500 °C. Dusts also can do problems, they generally come from cloths and hair.

[@bpark10001]

The way to clean up that oxidized potassium is to put it into the oil like the other piece. Heat until all is melted. Add small quantities of alcohol to the oil. You did this. Just put the dirty potassium in. The crud can be removed & the potassium put in clean oil & repeated until it is clean. Does molten potassium dissolve copper?

[@bpark10001]

Aqua regia: you could use "poor man's aqua regia" (HCl + any nitrate salt). Doesn't molten alkali metal attack glass? What type of glass are you using? Is it borosilicate?

[@AdvancedTinkering]

Yes, I think I will test this method next time. The still is made of borosilicate glass. At higher temperatures, potassium also slowly attacks the glass. The slight brown-golden discoloration in the glass comes from ion exchange, if I remember correctly. But it is no comparison to lithium, which completely destroys the glass and is almost like a thermite reaction. I have also made a short video about this.

[@h7qvi]

Would be good idea to have a tray under the apparatus in case something breaks

[@kapytanhook]

[@mrgreenguy]

Very interesting video! I love how pretty it looks :) I noticed you used a regular borosilicate flask to boil the potassium in, so I assume the vacuum lowers the boiling point significantly. Do you know around what temperature that might be? I'm thinking of making some alkali metals myself by distilling Sodium Metal instead of the often used lithium with the target alkali chloride salts to get them coming over metallic. I'd like it to be in glass so it's visible. You think this could work?

I had no idea metal evaporated like that. I love seeing weird properties like that.

Perhaps worth some investigation. Makes me wonder about the nature of chemical reactions as a whole. Also, odd question. I always see people just casually cutting sodium and potassium with a knife. Do the alkali metals react with the steel at all? I can't imagine that there's no chemical interaction whatsoever between the alkali and the blade

You can but you have to have a licensed company or a university lab to be able to do it. Private individuals can't do a lot of things any longer in the EU because of safety or terrorism. Hydrogen peroxide can only be 11,99%, sulphuric acid (37%) can no longer be sold to people buying new batteries with empty cells, nitric acid in Finland can only be sold if it's something crazy weak like 1% and so on.
