Chemiluminecense with potassium permanganate. 4K

- Опубліковано 10 лют 2025
- In this video I’ll show you an INORGANIC chemiluminescence, which is a very rare phenomenon in inorganic chemistry. Chemiluminescence is generated directly by excited manganese (II) ions (λ ≈ 690 nm)

cool, I asked for this reaction almost exactly 2 years ago, thx for great vid.
Thanks for another inorganic video. Inorganic doesn't ever get as much love but the things that can be done are so much cooler because of the superficial simplicity hiding awesome physics :D
The glow is beautiful.
It reminds me of the luminescence of singlet oxygen as it returns to a ground state, similar colour and everything.
Probably is!
That's the one done by bubbling chlorine gas through a basic solution of H2O2, isn't it?
@@bromisovalum8417 I don't know about that, but hydrogen peroxide mixed with sodium hypochlorite (bleach) produces it along with sodium chloride and water.
@@HypnoKnight I think it is the same reaction, but done differently.
Very good stuff! I prefer this calmer music, it gives the video a nice atmosphere.
Luminescence has always eluded me in chemistry
I can't fully understand (tbf i never formally studied it) but the videos on it are great
Thanks, and welcome back, it's been a while
It's physics. Something about electrons changing their energy level. When do a chemical reaction, some of the energy stored in the bonds is given off as light, most as heat tho.
@@Mp57navy Yup, the energy difference between the levels is quantised, and is emitted as a photon of the corresponding frequency (because frequency has a very well defined relationship with energy). This is also why this mode of lumeniscence tends to be mono-chromatic (single frequency light makes the colour, not a mixture of different ones)
@@mduckernz yeah I understand that that's what happens but why doesn't it happen elsewhere? Why is it a gradual release of energy? Is it maybe that the luminsent species is formed slowly?
But again, why dont other reactions emit light? They all also have electrons changing their energy level (aside from black body radiation ofc)
Cool! I have never seen potassium permangenate causing chemiluminecense before.
Thank you so much for this video! Chemiluminescence is my favorite property to witness in a reaction and you did a fantastic job of filming it properly. Can't wait to see what's next!
You are really great as a teacher.I hope i ll find some teacher like you.Love your videos
in before this channel blows up, you deserve it
Beautifull information bro
Thanks for this excellent video, I look forward to the next!
That is excellent. Nice piece of chemistry.
This was really interesting!!
Thank you i love your videos, keep up the good work. Looking forward to the next educational video.
real all your videos are very benific
Great as always 💯💯
I didn't know about this one. And it's easy to do at home too.
Awesome video dude! I am just as stumped as you are about the cause eof the creepy red light! I know it has to do with ecxited electrons going to their ground state, but not much else.
Esit: I would also be SO happy if you did a video on dichlorine hexoxide and dichlorine heptoxide, as well as carborane superacids! As usual, keep up the good work, man! ^_^
A copperiodide with pyridine and triphenylphsophine complex is also fluorescent. Also works with cyanopyridine.
If the complex is at 77 K its phosphorescent
Great reaction, never seen that one before. I've only read about it, I wish I had the same chemical stock as you :)
Damn that was awesome, can't wait to see the next one!! Definitely reminded me of singlet oxygen. Also I'm telling on you to Mathologer for stealing his music :P
Very cool reaction. I like the video!
Oh wow this is going to be awesome
Love the mic holder... :)
I know what I'm doing this weekend.
Chemiluminecense with potassium permanganate? :D
@@ChemicalForce yes sir! I have everything I need already. Just have to find the time to do it. If I make a video of it I'll add a link to this video and give you credit for the idea.
@@BackYardScience2000 can you direct me to it too, I'd like to see more
@@guythat779 yeah. I'll share the video in this thread and tag you.
BackYard Science 2000 Wait, really? You have sodium borohydride? Or is there any other reducing agent I can use?
WHAT?!? Not even a single spark, fire, explosion? Not even a wisp of smoke? The times are truly changing!
How did someone discover this? Just putting random chemicals together? :p
or through some chemistry+physics that are far above my head
I was about to ask the same thing lol
This is nothing random! A reaction between a strong oxidation agent like MnO⁴- and a potent reduction agent BH⁴-, is expected to release energy. Usually heat. It is now possible to calculate that it will give out light, that was probably a serendipitous discovery. I haven't seen the paper!
@@toreschanke4086 how can you calculate that it'll produce light?

@@guythat779 when an electron moves to a lower energy state it releases some of it's energy as a photon, or light particle.
Hi, excellent video, as always. Couple of questions:
1. Why the phosphate?
2. Why the efervescence when the two solutions mix? The main reaction doesn't show any gas
i think the phosphate is a stabilizer but don’t know what the gas would be? could be oxygen
@@tahallium Normally phosphate is used as a buffer or pH stabilizer
Great vid!
Very cool :3
first :D
I always wondered if simple compounds like the inorganic metals i have on hand could make glow
*Illuminating*
I think the sodium hexametaphosphate formula is wrong? wiki says it should be (NaPO3)6
Ooops! Na6P6O18 of course. misprint. sorry
@@ChemicalForce hey you should make some videos on uranium chemistry or hypergolic rocket fuels like dimethylhydrazine if you have any 😅
@@ChemicalForce Sodium (VI) rocks.
I read somewhere that it is possible to observe weak blue luminescence when we mix saturated solution of NaCl with concentrated HCl...
Very interesting! 😊😉😁
Crear! Thank you
Last time i was this early i watched the big bang happen
it looks a lot like the reaction between concentrated peroxide and TCCA producing singlet oxygen which also glows red.
You should do platinum catalytic reactions
This reaction is interesting.
If chemiolumimescence is not due to singlet oxygen , but de to manganese (II) íons...
Is it possible excite te Light using a soluble manganese salt?
is diborane release possible in this reaction? I apologize for possible mistakes, I used the translator
Could the red glow be from the hydrogen?
Would be awesome if you could add equal amounts of concentrated H2SO4 and highly concentrated H2O2 ! When working with piranha solution my professor all ways warned us to never add sulfuric to h2o2. Only the other way around and to be very careful not to make a highly concentrated solution of peroxymonosulfuric acid.
Could it be that the spectrum of singlet oxygen is being altered by the permanganate ions ? Or is it just totally different?
Where does one get NaBH4? I have the rest handy
How about a reaction that ABSORBS so much light that it would be like VantaBlack in a beaker? 😄
What camera/lens do you use?
What if it is used ionic hydride like LiH or hydride like LiAlH4 !🤔
Wow, NaBH4 in water, that's unexpected
PTFE + Mg👍✌😎
Show reaction of. ..... Gregnard.... reagent . 👍
Was wounder why I'd Glow after I've drank a vitamin water
So...why is that cheminumilescent again?
because...it produced light from a chemical reaction!
Is no one going to mention that he has the mic clipped to his beard? Or is that normal here? Either way, you must know what you're talking about, the beard speaks. XD
It's not the manganese. It's just... manga.
Isn't burning chemiluminescence
