It depends on the amount of oxidising agents in the air. Anything will burn with a vibrant blue flame in pure oxygen or pure fluorine as they are the best oxidising agents. You do have a few exceptions because their ions burn with a certain colour but most things when burning pure will have blue in them due to the heat level.
@@sapperdeflap Nah, this guy makes better videos about demos with a specific compound. Nilered, Explotions and Fire, Cody's Lab etc. are all great, but this guy makes the best cinematic and informative demos.
It looks like the Will-o'-the-wisp occurs because you made a premixed flame. Premixed flames have a characteristic flame speed that will move down the test tube (like the reactions with NO2 later on in the video); however, in this case, the evaporation rate of O2 and CO closely match the flame speed, causing it to hover in the test tube. Excellent work!
It can't simply flash down? (Obviously not but I'm still a little confused as to why).. when this is done with most fuels, it is all but an instantaneous ignition of all of the gas mix. 🤔
@@ChimeraChemLab I agree and also provide and translation from Russian (using google translate) for all other non-Russian speakers: "Not enough energy is released to ignite the mixture throughout the entire volume (especially the cold liquid phase), I believe."
Does ChemicalForce realize that he's showing us things nobody has ever seen before? Violent, dangerous chemical reactions in slow motion. These videos could have serious research value and he's doing it for our entertainment, at his own risk. Truly the best.
Great video! As a well trained chemist myself, I probably wouldn’t play with such a large amount of CO unless it’s absolutely necessary. Your knowledge and confidence impress us.
Ok... you are having WAAAYYYY too much fun!! Very, very cool! (I'm sure that your test tube supplier is happy with you too! You're putting his kids through college at this rate...)😊
That iodine reaction gave me a great idea for an April Fools video next year. Get some exotic, high energy reagents, hype it up, mix them together... And then nothing happens throughout the whole video, haha.
I knew all this about CO but I have never actually seen this demonstrated. Thank you as always for the efforts you put into this. Some of us know chemistry but never get to see this stuff actually demonstrated so we all sit around anxiously waiting for what surprise you will drop next!
I would really like to see the emission spectrum of burning carbon monoxide and compare it to the spectrum of a burning hydrocarbon such as the one I made many years ago. There must be a multitude of vibronically coupled lines in the spectrum, but at the same time an overall majority of light in the blue and UV regions. Searching for images of this spectrum reveals practically nothing and it would be very interesting to see.
The aesthetic of the liquid CO into liquid O2 was genius material for some future sci-fi content. Special effects experts need to be watching your channel for inspiration.
This pure eye candy, not just for chemists. Just a year ago, I was searching for some images of solid or liquid CO, but without success - this is typical for uncommon chemicals or chemicals in other than typical states (CO is almost always used gaseous). You are hands down the nicest chem channel I saw since NileRed, showing all these reactions to the whole world to marvel at. Finally, such views are no longer restricted only to few chemists who happen to work on niche projects somewhere in private research laboratories...
5:30 Probably it happens because the boiling point of the O2 is higher than the boiling point of the CO, and adding oxygen evaporates the CO. Excellent video, this is one of the best chemistry youtube channel.
This is one of the best videos you've put out yet. Although my days in a chemistry lab are now decades in my past, thank you for allowing my interest to remain. I can only imagine what chemistry classes must be like now with the availability of videos such as yours to show off the reactions we could only once dream of as young students. Thank you so much!
I love your camerawork. This is the most visually interesting and well filmed chemistry demo channel I have ever found. Thank you for doing all of this for us, I for one love coming here to learn! Wow that liquid o2 pour was crazy!
It’s so nice to have such serendipity, I was just wondering what CO/O2 flames would look like after reading about that combination’s potential for use in Martian rockets, and this is exactly that. Thanks mate!
4:39 Simply amazing images, seemingly unreal, like CGI, but in fact very real.You get to see the most amazing fire scenes on this channel, and they keep coming. Awesome reference material.
Wow. That test tube breaking in slow motion sure did sound like an audio sample of artillery being fired. Once you start noticing foley you can never stop.
After exploding fresh fruits was lots of fun this is the type of content I really love this channel for! Please never ever overestimate the protection power of your fume hood. Everytime e.g. I see two liquids of oxidiser and flammable type mix all my lab instincts tell me to run. It´s better than any imaginable horror movie to see it upclose through your camera. And most of the time its stunning beautiful.
Wow, these reactions are some of the most beautiful, spooky looking I’ve seen yet. They almost look unreal with that blue aura of flame around the droplets of CO.
Every bit as beautiful as I expected. We used it in 5x10m burners in an ore sintering plant adjacent to the smelting furnaces that produced the gas. It was quite a view. Beautiful but deadly. Reminiscent of the movie Beowulf when Grendel enters.
OK, you are one of my new favorite chemistry channels now, I've been looking for this demonstration and reactions for so long, and I guess the only person crazy enough to do it was you! xD +1 subscriber! edit: Man, I love it when this happens, you kept reading my mind during the video, every time I had an idea, you tested it a few seconds later! Awesome! edit#2: now I want to know how hot the CO + O2 burns...
Very cool, never wanted to try some of those combos cause wasn't sure what would happen but again didn't realize that CO reacts in the way it does. Awesome video keep teaching some good lessons
Next video: "I smelled gaseous Plutonium" But seriously, CO is a big no no to even professional chemists. And this guy casually experimenting with it. I think even Thanos is afraid of his braveness. Keep up the good work, dude! You guys are the reason youtube is still worth watching.
02:50 Now I would run. If the extractor hood can't handle it, you have a problem. Gas masks don't help either, because the CO molecule is far too small to be stopped by the filter. But dude, I wouldn't want to be your neighbor next to the extractor hood outlet.
My plant where I work makes synthesis gas as an intermediate for another reaction(hydroformylation). I have always likes the way the flare looks in that beautiful deadly blue. Coming in to work I always glance at the syngas flare to know if my units are making production or if theres an upset by the color of the flame. I have also been in a 4000ppm cloud of CO from a leak, obviously with an SCBA. I would rather it be on fire, at least it could have been seen. One thing that fascinates me is the CO i use has to be ran through purification to get rid of carbonyls picked up in process piping. Think of it as a low temperature Mond process.
The picture of liquid carbon monoxide burning while the test tube was washed with liquid nitrogen reminded me of a play boy centerfold a slow motion take of a cool act producing hot results, and if you are exposed to too much of it, it will damage your brains! lol
The fascinating up and down movement of the flame might have something to do with the LEL and UEL of the CO and the oxygen gas floating around in the tube??
Could you do a video about metals (Ti, V, Cr, Mn, Fe, Ni, Co, lantanoid, ....) dissolving in HCl 37%? I'd like to see the color of solution after these metals completely dissolve
The hovering flame thing happens because the CO is so much colder than the LOX that it's actually cooling it down, reducing the volatility, and changing the stoichiometry to be very fuel rich (since CO is now making up much more of the gas mixture in the tube than LOX). It kind of creeps its way down as it burns through the gaseous oxygen. I would expect the area right above the flame to be mostly unburned CO and a little CO2. Is that close?
This guy is awsome, smart as heck. This would be the last guy you would mess with. He would take you out in a thousand ways, and you would even know about it.
I wonder if CO+O2 could be used as a fuel for rockets? Seems like it would be a relatively easy to contain fuel, and you wouldn't have to deal with hydrogen embrittlement. It's also more dense in liquid form by ~25% so you could cram more in the same space.
Interesting how liquid CO + liquid O2 is "well-behaved" Liquid N2O as well. Could be a useful behavior? I am curious about CO vs. platinum group catalysts
Would be cool to see oxygen burning in a carbon monoxide atmosphere. Or various oxidizers burning in fuel atmospheres. (I got this idea from Cody's lab who burned oxygen in a propane atmosphere)
Liquid co and liquid o2 evaporate at slightly different speed and they need to be a proper mixture before the reaction speeds to a flame? Is liquid o2 heavier than liquid co?
Does co burn hot or is it just the significant temperature difference that breaks the glass? Also i wonder if it smells like a dodgy gas heater thats generating co, sorta a musty, heavy smell hard to describe but you never forget.
This is probably the prettiest video I've seen. I had no idea carbon monoxide burned with such a vibrant blue.
значит вы не обращали внимание как горит уголь

But how about liquid CO with KO2, RuO4, ClO3F, N2O5, ozonated O2???;)
It's hard to imagine something freezing AND burning until you see the beauty of it. Thanks, Felicks, for showing the iodine. It's my fav!
This is, without doubt, your finest cinematography. Breath taking.

Bro, your channel is the only channel that I do not use the fast-forward function on. do you have any idea how amazing your content is?

Perhaps one of your most beautiful demonstrations. 👍🏻
This is amazing!!! It’d be nice to see a video on HCN as well.
Burning Carbon Monoxide on the table looks so beautiful.
Keep up the fantastic work!
3:16 Is the solid residue dry ice? Amazing
Love the inclusion of an iodine compound! Beautiful reactions and camera work as always - looking forward to the next one!
Man I don't get chemistry, love that I can just watch it do its thing though, thanks for the videos and effort it's really appreciated.
This is unparalleled.
Reactions of carbon monoxide is an area of chemistry that I never even knew I was missing!
Wow, these reactions are some of the most beautiful, spooky looking I’ve seen yet. They almost look unreal with that blue aura of flame around the droplets of CO.
I’ve never seen CO burn before this was an amazing demonstration!
WOW!! The burning CO on liquid O2 looks amazing!

Can you try showing carborane acids? I want to see what "strong yet gentle" looks like in practice
A fabulous artistically sophicated videography !
At 3:24 I wonder what causes the orange flames? Normally orange flames means impropper burning forming CO, but since this is CO, what else can it be?
Dude deserves a million (real) subs.
Those are so cool thankyou for taking time to show us the science and amazing tests ive learnt so much from watching your channel thankyou
Quite a spectacular video! The slow motion footage is awesome!
Thank you.
3:31 It looks like a solid residue was left behind when the carbon monoxide finished burning. Is this dry ice that's too cold to sublimate?
Absolutely beautiful colors I love this channel keep those videos coming thank you very much

What about liquid CO interacting with a heated catalyst like platinum or catalytic converter material.
Everything on this channel is so beautiful
Great video, as usual.
This is chemistry
and this is art as well.
Love the content! ❤❤❤❤
I'm surprised liquid CO and N2 are so similar. Wouldn't you expect the CO to be somewhat polar?
Great video. What no RFNA or HClO4?
Super! Thank you very much!
Do you think maybe you could do something with tri or tetranitromethane? I've never seen those on youtube before
The visuals and slow mo are amazing, but why dont you also add one in real time with sound?
Stunning
What if you mixed liquid oxygen and liquid carbon monoxide before lighting it?
Likely result is an explosion.
Are the flames hot?
Does co burn hot or is it just the significant temperature difference that breaks the glass? Also i wonder if it smells like a dodgy gas heater thats generating co, sorta a musty, heavy smell hard to describe but you never forget.
it's due to the temperature difference!
haha I didn't smell that :D
Why does gaseous iodine start of purple then turn red and brown??
The color directly depends on the concentration of iodine vapor
5:32 What's the BGM here?
Huh. I'd have expected that CO would have a boiling point more than a few degrees higher than N₂, because of the former being polar. Very nifty!
The fire is other-wordly and beautiful more than any other fire i recall seeing
