The chunk of Na was really dirty, you should have rinsed it with some water first...
LOL
I think trace amounts of water in the oil would actually help to clean it.
Actually, I think it was the potassium that was dirtier.
@@gordonweir881 ah lol
@@among-us-99999 Help to cover it with NaOH
1:37 "Now KISS!" That probably made me laugh more than it should have... lol.
If I'm not mistaken you can add a couple drops of isopropyl alcohol into the oil to destroy the oxides on the surface of the drops.
Perfect reaction.
NaK can spontaneously combust on air and is explosive when mixed with water. It forms two perchlorates, which are also explosive, and hydrogen gas. Which, being superheated in the reaction, reacts with oxygen to produce water. Explosively.
It's explosives all the way down.
So, you’re saying that dropping NaK into a bleach solution is a bad idea. Got it :)
This is the only chemistry channel that uses epic music when things are reacting as far as I know. I love it!
because reacting is epic :D
In my opinion, it is a bit forced (maybe even awkward)
@@ChemicalForce what was the music?
This amped up Chemical Force is getting to be my new favorite UA-cam channel. Love your lively reactions. I just got finished with a demonstration on persulfuric acid gobbling up most anything we could drop into it. Let's figure out how to crack a small vial of cesium under a shallow layer of bromine.
Gorgeous pictures! Best chemical camera ever!

@@dreamspace4858 I love you!
4:05 - angry potassium/sodium monster face!
A syringe full of molten alkali metal probably should look sinister and angry. lol
Normal people: Lets clip this lavaliere microphone to the collar for best sound quality.

Trust me, it's stuck there for a loooong time :DDDD
@@ChemicalForce waifu
the surface tension accompanied by the low density make them look really cool, especially when merging, like that agar.io game
So satisfying to watch
@@vivek-zo2yy when he mixes the alloy
@@vivek-zo2yy it's like one third of the video, you can't miss it
@@vivek-zo2yy from where he starts mixing the alloy up up to where he finishes
@@vivek-zo2yy 0:38 - 4:00
I love videos like this because they really renew my sense of wonder and curiosity and allow me to really fundamentally question the different phases of matter and how thinking of them as discrete states is really a flawed way of thinking.
When you used the syringe to grab some of the alloy you actually stabbed all the way through every time, and can see the tip of the needle drawing in the acid not the metal while you fill the syringe
Thank you for making this channel, and uploading a wide variety of reaction videos! I am currently finishing my undergraduate degree in Chemistry and find these videos really fascinating!
thanks for your significant comment!
@@ChemicalForce I watched your video, here in Brazil.
Very nice video. I think you deserve 1000k subs. All of your videos are the best in youtube.
Congrats to 10k subscribers! You definately deserve everyone of it!
Hope you can at least double it this year, I'm pretty sure you'll get it! :)
Must be about the best chemistry photography with the coolest chemicals on UA-cam. Great job. Merging the NaK blobs reminds me of a Borg assimilation.
I'm so incredibly happy I found this page
When ChemForce breaks out the blast shields / protective tank, you know it is getting intense! Love the channel - I'm a chemical safety guy, but I love a good firework show as much as anyone.
Have you ever considered a video with Chlorine Trifluoride? You are one of the few UA-camrs is good enough to work with it safely, given that it sets sand on fire...
I honestly never considered melting the two under oil when making NaK, Great method!. Also if you add a few drops of dry ethanol it cleans up the alloy very nicely and gives it a mirror finish
You have the ormus, i guess!
Yeah!
I love this channel. And thanks for doing a collab with _Exploaions&Fire/Extractions&Ire!_ That's one of my fav channels too.
what are you up to?
I think the most interesting thing about the SF6 is that it has a noticably higher refractive index, so it almost looks like a liquid 8:16
Nice channel. Really hope YT doesn't restrict your creativity because you work with chemicals.
because this videos are made for educational purposes
Magnificent! Nearly shat my pants with the bromine.
The production of the alloy looks really interesting
I love the confidence, fume cupboard, protective glass, fume cupboard glass, gloves, white coat and CARDBOARD! Proper science and chemistry!
Your vids are getting better and better. Keep it up :)
Thank you!
Seems tame enough to cool nuclear reactors with lol
Imagine a 10,000 gallon spill of this stuff
For anyone wondering; they explained this on the periodic video channel; because it's a lightweight metal, you can easily pump it around and it conducts heat very well. Unfortunately there might be a case of it eating away metals...
Don't worry; you will have more than 100k subs before March ends
Nice! With the first reaction, I think you could get better results with more depth to the liquid, though. You can see that, the first time you did the HClO4 reaction, the sodium just fizzled out on the surface. A bit more depth might help, since the reaction will work best if the alloy manages to become completely surrounded by the other liquid. They can only react at the points of contact, since the liquid metal bead tends to stay coherent. Go for a different container next time, and it may work better.
Healthy tip on working with alkali metals. Don't use mineral oil. It's not meant to be used for them. Use kerosene. It's easier to work with.
The microphone clipped to the beard is absolutely brilliant
The reaction with bromine looks like a firework bloodbath.
Very nice video.
Next: Something of radiochemistry?
That's illegal. No really, at least most of it
So satisfying to see these NaK alloy welding together
The sulfur hexaflouride trick at the end was a nice touch
Congrats on 10k subscribers! You deserve many more!
That was awesome!!! Loved the cool shots of the alloy in beads
Can you make a video about properties of molten alkaline hydroxides? They’re scary, they can dissolve glass in seconds.
ps. I love the epic background music :D
I love the way the globs jiggle when they coalesce!
I like jiggly globs myself. You put jiggly globs with chemistry and everyone is going to have a great time.

@@akashpisharody
Not sure im sauteein what youre marinatin there, chief. Zat some kinda reddit jargon?
@@mshock9637 Yeah man it's a subreddit for comments that are hilarious taken out of context :)
@@akashpisharody
Sounds like my kind of fun. Ill have check it out then. Thanks.
When making the NaK if you add 1ml of anhydrous ethanol it makes them coalesce much easier somhow preventing the oxide from sticking to the NaK surface.
Given how hygroscopic that stuff is, you’d need to dump it straight from the distillator into the NaK dish, with some dry shield gas, right?
@@absurdengineering my memory was off, it was isopropanol not anhydrous ethanol. You mix the Na and K underneath hexanol(other inert solvents *may* work), then add a few drops (2 or 3) of isopropanol after.
Dude your music taste is great lmao what's the song on this? That final cloud was hypnotic.
Back when I was a teenager around the time that Terminator 2: Judgement Day was released, if you had suggested that in twenty years time I would be using my ultra-slim wireless touchscreen smartphone to watch a digital video of some random guy on the other side of the world shooting a liquid alloy of two highly reactive metals out of a syringe and making it explode, I would have laughed in your face and accused you of being high.
Wow... They merge so quickly... You can't even see it happening, all you see is a metallic jell-o grow. It's fascinating. xD
Nice Video, but it would be nixe if you could leave the writen reaction equations there a bit longer . Keep up your great work :)
played on 0.25 speed :D
One of the best channels about chemistry with no doubt
=YUP,THAT METAL FACE IN SYRINGE
=AND ALSO THAT ACTION IN THE BEGINNING WAS ABOUT THOSE METALS TO BE FORCED TO MATE,HEHE
_I love the smell of bromine in the morning_
Is it wrong that I loved the physics bit at the end with the sulfur hexafluoride?
Chemistry and physics working together!
Not long ago much of physics was under chemistry
crazy how much water was dissolved in that kerosene, that the sodium and potassium started oxidizing as soon as they hit the bottom of the beaker. i guess the heat made it happen much faster, but crazy to see how much it oxidized after being dropped in what should be a nonreactive medium.
You think of literally every cool reaction imaginable! My hero!
I would like to see reaction of Caesium with Fluorine!
ua-cam.com/video/TLOFaWdPxB0/v-deo.html
Next: cesium rhobidium alloy
Wasili Rauscher react with fluorine
You're channel is amazing I cant wait to see more videos!
I can't wait to make more videos!
It's crazy how quickly they join together... it would be interesting to get the high speed camera on it to see the liquid blobs flowing into each other.
Oh yes I would love to see that too
I need to collab with The Slow Mo Guys :D
Need to get the slo mo guys on the coalescence of the droplets of liquid metal. That was terribly fast!!
For just a moment I thought that the noise of the fume hood was the start of a drum roll sound effect.
Dude, I love you and you channel!
I wonder how the Na-K alloy would react with liquid oxygen as well as the more reactive alkali metals rubidium and cesium 🤔
Brandon Fisher The liquid oxygen reaction would be tame compared to the reaction with bromine as oxygen is actually somewhat stable compared to the halogens (oxygen would need to be oxidized twice while bromine only once in a complete redox reaction). No reaction would occur with Rb or Cs as they are also alkali metals; one alkali metal won't oxidize (or reduce) another alkali metal. The most exciting thing that would happen would be the formation of a glob of NaKRbCs alloy which would probably look identical to the NaK alloy.
@@noahswindler7461 I always thought that oxygen is the second strongest oxidizer behind fluorine so all of the halogens other than fluorine would be weaker oxidizers than oxygen.
BTW rubidium and cesium are known to spontaneously catch fire in air so I figured they would react much more violently in liquid oxygen.
@@brfisher1123 I misunderstood your comment, thinking you were suggesting reacting Na-K alloy with Rb and Cs. My bad.
Congrats on the 10K Feliks.
Thank you!
Also, 1 drop of IPA would make them fuse easy, and clean the metals
And slightly to much will explode
@@tp6335 you're not wrong
This is easy to understand!
Thank you 😊
What a mess with bromine... Would be interesting if NaK can react with SF6 either?
Can this alloy form "amalgams" with other metals? It would be very cool, for example with gold, somethimg as dense and inert as gold and something as light and reactive as sodium and potassium.
teraNEX cz an amalgam is an alloy of mercury with other metals. If you are wondering if NaK can alloy further with other metals then yeah probably
Should have put some ethanol into the kerosene to keep it clean
I am lucky to find such an underrated channel
I wasn't expecting the drops to merge so suddenly.
Good video.
But I have questions. That black crust that forms on the metal. I'm guessing it's actually oil being actually burnt by oxygen lost from the sodium and potassium oxides? And the oxide is regenerated by the water in the oil and that released from the slow carbonisation/burning of the oil. Similar how magnesium is consumed in in dry ice and it makes elemental carbon?
Could you pls show some reactions like this with rubidium and caesium?please
maybe in one of the upcoming videos (some Rb reaction)
so let's draw some liquid metal into our syringe!! thats awesome
the SF6 trick was a bit ruined by dumping it all across the aquarium. Better to gently pour it in from one side and really replace the Br2 vapors from bottom upwards.
1:48 The Sodium and Potassium are puffed out of anger
haha. this is really cool stuff!
this is really cool comment! :D
Awesome video, the alloying process was fascinating.
Does the black oxide/contamination form due to impurities in the metal, or impurities in the oil, or because the oil is not 100% dry, or what?
Love the soundtrack :)
Nice video,try K/Na +DCM,CCL4
:DDD
SF6 is the most dangerous greenhouse gas being more than 26000 times as effective as CO2. Was it worth it?
You’ve surpassed yourself. Fascinating close up of the Na+K kiss 💋So romantic😄. Loved the reaction with Bromine.
💋
What's the black stuff? Carbon from the vaseline oil?
Best glass commercial.
Would NaK, Sodium, or Potassium react with dry ice? If not, would it react with adequate compression when the CO2 is in a liquid phase?
Do you work inside a glove box? Does the fumd hood require a different filter? I believe the regular ones don't allow HClO4 inside! Damn all these experiments are as beautiful and impressive as they are dangerous!!! Thank you for the demonstrations!! How do you handle the waste?
Would NaK react with PTFE ? A reactive alloy V.S. A chemically inert plastic.
always that oil. do it under argon with no oil. I love this video though! I wanna see 200-300cm3 NaK poured from one beaker to another :)
Love from Serbia, i have question, how or with what did you clean at the end
I would never think that you could merge them
Did you buy you Na and K or did you synthesize it your self
Lol completely pierced the blob to suck in the metal and oil and a few oxides/hydroxides... Hovering inside gives way better results (if you're doing this again at some point)
But I absolutely like what you're doing here on yt 👌
Thank you Molodes
New favorite chemistry channel. My old favorite turned political in his videos years ago. My second favorite has a sparse upload schedule.
Make an alloy of all alkaline metals!
Ahhh sweet! Btw do Cs and K alloy too?
Yes, also Na and Cs. I´ve made a few of these alloys, they have incredibly low melting points. They are liquid at something like -70°C, much lower than Hg. If you try to make Cs ampoules they are very annoying, because they stick to glass. At least that´s what I´ve read and thats also why some of my ampoules failed.
I don't like where this is going
@@SomeAustrianGuy Danke!
It’s so weird that sodium and potassium are solids at room temperature but combined at a liquid at it.
I am not an alloy expert, but could you in theory make an alloy of Sodium, Lithium, and Potassium? Maybe you could try it.
Nice video!
Do a video about flourine gas.
What’s all the black stuff when he is mixing the two metals? Was it just spots of oxidation?
Your videos are addictive and worthy of repeated viewing.
any combination with Barium wich make it liquid? Cesium and Barium can be liquid like Sodium and potasium?
7:58 and you suddenly sound like dr Butyl Lithium, aka NurdRage
Hm... but what if he breathes it in, how would he sound?
@@ChemicalForce Guess we could ask @NurdRage to try it out
I was hoping to see if NaK reacts with sulfur hexafluoride
You really have a NaK for chemistry
washing out glassware from bromine by heavier gas is very original. Could we get gas so dense, it would form a stable layer like fluid at bottom?
lol'd at the mic clipped on the beard
