Beautiful video as always. From an inorganic chemistry lens, the pink color is due to the larger HOMO-LUMO gap of the cobalt aqua complex compared to the tetrachlorocobalt(II) complex. And the aqua complex is formed because H2O is a higher field ligand than Cl so H2O swaps with Cl at the Co. Since the HOMO-LUMO gap of the aqua complex is larger, the aqua complex absorbs more high-energy, short-wavelength light, leaving us to see longer wavelengths reflect off the solution and see the redish color.
Wow, finally a chemist with a strong cinematographer inside him. Beats many TV productions. Intro should be a reference to '90s Hollywood or something. Quality editing, theme choice, a rare treat. I just wish i went this way after nearly blowing myself up in secondary school..
I think the product of the chromyl chloride reaction with the metal carbonyls is probably a highly aerated matrix of metal, metal oxides, chlorides and other compounds, somewhere between a blown foam and wispy fibrous mass as strings of metal and/or metal oxide are created as each part of the strand is lofted away from the point it is generated by the hot gaseous reaction products. The mixture of transition metals with strongly coloured compounds provides a rich palette of colour that the eventual oxide sponge is delicately encrusted with in places.
Your videos are absolutely wonderful. I work in heterogeneous catalysis, as a postdoc. Despite years of experience and a Ph.D, I (almost) never got to have fun with chemicals the way you do. Thanks for creating such amazing content, and sharing it with us.
+ChemicalForce Actually the blue colour that results from the reaction between cobalt and hydrochloric acid is due to the formation of tetrachlorocobalt(II) complex ions caused by the excess of chloride ions. A cobalt(II) chloride solution by itself is pinkish-red. CoCl2 + 2 Cl- ↔ [CoCl4]2-
I can't believe no one thought to do macro shots of chemical reactions before, it is absolutely perfect for it. Even if you don't know a lot of chemistry, the cinematography alone is good enough to keep you captivated. These videos are just so well done, it's incredible.
Actually Co 2+ is indeed red but the solution with HCl gives the complex [CoCl4] 2- which is blue That's how it goes: [Co(H2O)6] 2+ + 4Cl- [CoCl4] 2- + 6H2O
well sir, my hat's off to you. I am not a chemist myself, but i am always mesmerized by the reactions that you show in your videos, you make chemistry beautiful, and an art form in itself. Also appreciate how you explain the reactions as well. love to learn the hows and whys and what is actually going on, as well as the outcomes,. Love it, and thank you.
To be more accurate, the blue compound is [CoCl4]2- which is formed via the the dissolution of CoCl2 into Cl- sat. aqueous solution, and the red compound is most likely [Co(H2O)6]2+ and some intermediate complexes [CoCl(n)(H2O)(n)](2-n)+ . The stronger the ligand field, the more intense will be the bathochromic shift in the optical interactions of the solution
omg I think I just found my NEW FAVORITE CHANNEL!!! I see an octopus too.. except without the legs..... the head is leaning back and facing us... it's awesome!!!! I just LOVE you camera work AND you use EXCELLENT music!!!!
The fact that the CoCl2•xH2O + SOCl2 reaction is endothermic really surprised me. SOCl2 is energetic enough that I'd have expected almost any reaction with it would be exothermic.
Same here lol. The chemical equations looks like just random strings of letters and numbers to me. Although I do know what element abbreviation are. I could tell you what elements are in the stuff, but beyond that, its all foreign to me. It's still super interesting to watch these reactions though.
Amazing videography, especially the high frame-rate stuff. Beautiful, in fact. And after all your channel's videos I've watched I've often wondered: Who gets to clean up the aftermath and how much of a pain in the butt is it?
Just stumbled on your videos and I couldn’t believe the quality! I know people say “you deserve so many more subs” all the time, but I seriously mean it, and you definitely earned a sub from me!!
I remember an experiment from university - put a leaf between two pieces of filter paper with CoCl2. When it's dry - it's blue, when it's wet - it's pink. That you can prove that leaves evaporates vapor in a process called transpiration
He’s still making normal videos, shorts are just what he uploads in the middle. It’s a good idea to make viewers stick to your channel even with a very long upload date gap.
when I saw your post about this (octopus reaction ) , I saw everyone in comments saying that this is like octopus 🐙 but I see that this a huge chemical mess :D
The formation of those fumaroles 23:27 and in the other chromyl chloride/Co2(CO)8 reactions are interesting. I wonder what the mass looks like inside if you cut it open or propped a microscope slide up on the watch glass before starting
My favorite thing in the world is that a mushroom cloud can look like a great bonsai tree... Make you wonder why nature makes some trees look like mushroom clouds... *whisper*or visa versa...
This is epic chemistry! Speaking of epic, does anyone know what epic music this is? As usual, I enjoy the music as much as the video itself. I wish he would attribute the music in the video descriptions.
The reaction between the solution cobalt carbonyl in iron carbonyl with chromyl chloride looked like Yog Sothoth. The mushroom cloud reminded me of when I was making manganese heptoxide in my mums living room. The test tube must have been slightly dirty because it began to bubble then decomposed giving a little purple mushroom cloud which then solidified and fell onto the coffee table like a bit of candy floss.
Loved the video! I was going to nitpick the plural of octopus being octopi, but I looked it up and apparently both are correct, as well as the word octopodes, even though the autocorrect on my iPhone doesn’t like it. Just another reason to be confounded by the English language.
Hi. I saw that the MSDS for reagent-grade caffeine says that it is incompatible with oxidizers. do you know if that’s true, and if so, could you do a video on a reaction with caffeine and an oxidizer please?
Great video but I'd like to point out one mistake. Saying that the colour of the cobalt(II) solution changed from blue to pink after the addition of water due to the dissociation of CoCl2 into cobalt(II) cation (the reaction CoCl2 = Co2+ Cl-) is an oversimplification. In reality, the blue colour results from complex anions [CoCl4](2-) (present in HCl solution), which in the diluted water solution reacts with water to form aqua complexes [Co(H2O)6](2+), responsible for the pink colour of the solution. The free Co(2+) ions do not exist in the water solution. Instead, the metal ion always coordinates to several ligands (water molecules or other Lewis bases).
Sir we would like know torch light bulb difuse in drp making.which chemicals used in this process.pls send and explain your valuable experience in chemistry
Neophyte's question... Everytime you do an experiment, you do so under the protection of a fumehood. Said fumehood has got filters, obviously, but what happens when fumes are corrosive? I suppose they may eat through the filter very quickly? Or are there different types of filters?
What are your credentials? Obviously you can buy chemicals I can't nor do I want. I wished you would comment on sodium azide as a high energy gas generator in air bags. Poisonous chemicals scare the hell out of me. I love your channel though❤
Production quality is through the roof! Edit: OMG, FINALLY an endothermic reaction. I asked for something interesting like that years ago.
go to pharmacy, ask for instant cold packs...
I was glad there was thermal camera footage because it really looks like it's boiling and steaming, yet it's 0°
Bro go out and socialize
Beautiful video as always.

me: homo lumo is burning gay
duh
The change in the colour is not only due to the ligand exchange but also change of the coordination sphere of Co(II) ions.
Wow, thats quite interesting thing, thanks.

This channel is pure art by means of applied chemistry! 💙
Or is it pure chemistry ?
@@YounesLayachi It's a union!
Does art mimic chemistry or does chemistry mimic art ?
@@truthandfreedom9849 The first one. Art mimics life. Life is chemistry. Ergo...😁
The Iron Pentacarbonyl and Tert-Butyl-Hydroperoxide reaction and the mushroom cloud is produced right here was so beautiful especially in slow mo

i've only got a gcse but i agree.
My only relationship to metal carbonyls in heterogeneous catalysis was to try to keep from making them
The mushrooms cloud slow motion was beautiful. Felicks, you make chemistry so fun to watch!!

CoCl2 + 2 Cl- ↔ [CoCl4]2-
Yes, molecular cobalt salts don't exist... What we see are complexes.
Yep. *Pink* [Co(H2O)6]2+ complex ions form in dilute cobalt chloride solutions.
While in hydrochloric acid *blue* [CoCl4]2- complex ions are formed.
Hey!
Yes, I know. I just thought it would be an illustrative example showing a simplified dissociation equilibrium 😮💨
@@ChemicalForce I get it. It´s fine, but I just thought it would be more precise.
@@ChemicalForce When you'll be going Radioactive? We would love to see some videos on Actinide/lanthanide series reagents.
Digging the macro shots and love the production. It keeps getting better!

That's how it goes:

less obvious but similar example with Cu (II) - [CuCl4]2- is emerald green while [Cu(H2O)6)]2+ is blue

You're not only talented with chemistry, you're also good with filming, editing, and production!!
As always, great video. And the HCl experiments are a great demonstration of ligand exchange in coordination chemistry, one of my favourite areas.
All I can say is Chemistry , Art, Beautiful reactions, you sir , are amazing. Thank you !
These slow motion reactions are mind blowing. Thank you for showing the beauty in these. Love your work. Subscribed.
And just think how massive these reactions are in estuaries, super dilute, if only industry had this level of love for chemistry

Metal carbonyls: fire with death. Love it 😸
It looks like a giant rock covered in coral and algae that's been shrunk down a whole bunch lol. That's cool
And thanks to the fume hood even looks like it's underwater

Looks like a Horta from Star Trek! :) GREAT video!
Cobalt has the coolest colors

A little mushroom cloud, so cool!
Chemistry and science will always be my favourite subject
Pretty good cinematography!
9:30-10:00 Forbidden cooler.
15:55 The mass looks like a screaming amalgamation of lost souls straight from hell.
Soul sand?
It looks like cancer to me! 😶🌫
EPIC, just epicingly EPIC!!!

Will any of these carbonyls react violently with UV light?
soo much fun with cobalt... 🙂
The strongly blue stuff in a solution is a tetraedric [CoCl_4]^{2-} anion. [Co(H_2O)_6]^{2+} is octaedric.
Man this is soooo coool :D
