Making Rotten Eggs Essence. Liquid Hydrogen Sulfide.
Vložit
- čas přidán 27. 06. 2024
- In this fascinating video, we delve into the world of hydrogen sulfide - a colorless, toxic gas with a distinct and unpleasant odor, often described as smelling like rotten eggs or fart. We start by synthesizing liquid hydrogen sulfide in the lab, using the hydrolysis of aluminum sulfide. You'll witness the chemical reaction taking place, producing high-purity hydrogen sulfide.
As we explore the properties of liquid hydrogen sulfide, you'll discover that it is highly flammable and reacts explosively with some substances, such as chromyl chloride and dinitrogen tetroxide and you'll see sulfur forming in various reactions.
We'll also examine the effects of bubbling hydrogen sulfide through concentrated nitric acid, resulting in the formation of large amounts of nitrogen dioxide, and how hydrogen sulfide reacts with iodine monochloride, producing elemental iodine. You'll also see some stunning reactions with other substances, such as lead dioxide, sodium and potassium peroxides, selenous acid, etc.

this video is CRAZY!!! mad respect for showcasing so many demos utilizing such a terrifying compound. the knockdown ability of H2S is the stuff of nightmares
Lurking also! Pretty Cool Right?¿
I read this in your voice, @styropyro
it must be jarring seeing someone on science youtube more clinically insane than you (in a good way)
This is one of the scariest routinely used chemicals in most labs. It truly is an insidious chemical.
@Peaches Where are you from? Here it's technically not okay to even use acetone outside of the fume hood...
I dealt with this gas working in the oil field. There's stories of entire workover rig crews dying within minutes of the gas being released. That was before we had knee high monitor sensors.
This is by far the best chemistry channel on CZcams. I don't get why it's not more successful!
Patience!
Hydrogen Sulfide is a terrifying gas. Not only does it literally smell like the fartiest fart you have ever smelled in your life, but inhaling it can almost instantly knock you out, allowing you to keep inhaling it until it kills you. This has happened actually not uncommonly across the mining and chemical production industry. It is a chemical to be treated with the utmost respect. Of all the explosives and toxic chemicals you have worked with, this is the first one to actually make me truly nervous lol.
H2S paralyzes the nerve that controls your lungs.
The only good thing about H2S is that it is very easy to produce and there are many various different methods. Everything else is really bad.
The OsO4 is far worse in comparison.
And to think that toxic hydrogen sulfide (H2S) is really just a sulfur analog of water (H2O) or hydrogen oxide that is essential for all life.
I find it interesting that water is not horrifically toxic like any of the other hydrogen chalcogenides.
@@brfisher1123 Not only that, some benthic (bottom of the ocean) species use hydrogen sulfide to live off of like we use oxygen.
about the mercury dinitrate,Since HNO3 is a liquid,the formed HgS immediately gets attacked by HNO3 to reform the dinitrate.In case of the mercury bromide,HBr quickly escapes since it is a gas.That is my theory.
This is basically what I was thinking too
My bet's on witchcraft.
What about the slight yellow color to the mercury dinitrate by the end? I see slight red-orange fumes by the end too, so I'm guessing it's partial decomposition to nitrogen dioxide and elemental sulfur.
I once made H2S in my garden, to do some experiments. I was maybe 16 years old and had a few jars connected with some straws. Opend one to smell the H2S, but I couldn't smell anything, so I put my nose in the jar and it was weird- I didn't smell anything, but felt weird shock and couldn't see for like 5 seconds after that (almost blacked out). Then I learned, I almost killed myself and didn't smell anything at the beginning, cause the concentration of H2S immediately cut off my nose nerves. That was fun.
😳
silent but deadly
Yeah just no. Sulfur is fascinating but you gotta watch your back.
Did u go to the hospital or anything? I have made H2S before, and im always scared I couldn't smell it because concentration is so high
@@Diycrazystuff Nah bro, I'm immune to this shit
I loved seeing the reaction of OsO4 and H2S, because of the inside of the plate resenling the surface of Mars, and the area around the plate resembling the spread of black mold. I'm also surprised it didn't create any flames, it was a pretty calm reaction. Neat!
There are several channels that specialise solely in slow motion video yet this chemistry channel produces some of the most beautiful and interesting footage I've seen, well done
There are times where a colab would be most beautiful indeed.
I would be interested in seeing liquid H2S react with liquid SO2. I've tried reacting the two gasses before and they should form sulfur and water. Supposedly this is why there are often sulfur deposits near volcanos (since volcanos produce both gasses). But I have never seen any sulfur produced when mixing the two gasses.
At first, I thought H2S is dull, but I stand corrected. WOW, when looking at the CF angle everything becomes hyperbolic thanks to other fascinating chemicals, OsO4 and plain HNO3. What an exciting chemical and super toxic. Must be a mess to clean up afterward, Se, Cd, Pb, Hg,...
I love these deep dives into a particular compound and their various reactions! Phenomenal work!
Extreme oxidizers plus extreme reducer goes BOOM. These are the reactions you never do - and yet, here they are!
Despite being such a terrifying chemical, my secondary school once had a bottle of H2S solution that was heavily contaminated with sulfur. A friend of mine told me it reeked worse than rotten eggs. Fortunately though, it was thrown away :)))
The photography on these videos is amazing, I love to see the detail in every reaction. Just beautiful images, and really interesting chemistry too
They are. Some of them look CGI they're so "other worldly" when slowed down and taken in. Would love to see some of the more "apparently beautiful" done in a colab with someone with the nutty cameras, slo mo guys etc.
That said, yes just with what he has, these are stunning. All beautiful in their own ways.
The hgb2 produced gaseous hbr which due to le chatelier's principle this pushes the equilibrium to the right since the gas escaped. With hg(no3)2 this is not the case since hno3 is a liquid it stays in the mix and quickly reacts with HgS and the H2S can escape shifting the equilibrium.
beautifull reactions i hope i never see myself in person, despite watching stuff (arsenic) burn in a glovebox myself, ur crazy and i love it :)
Some things are better from a distance 🤣
the pink from the cobalt honestly one of the best colours youve ever made
Pretty awesome to see substances that we normally only "see" as gasses to be seen as liquids and/or solids! Are you planning on showing us *liquid* hydrogen selenide next?
Yes, I know you've made hydrogen selenide before, but it was never condensed into its liquid form thus we've only "seen" it as a gas.
thats genuinely a terrifying thought
13:36 : I guess you have an equilibrium where, when a lot of H2S is present you're forming mercury sulfide and nitric acid. Those then immediately react to form mercury nitrate and hydrogen sulfide as soon as the H2S partial pressure drops.
But why is it gray
Woa woa, thanks a lot for this video, Felix. I've taught my students about the reactions of sulfur, but they always ask me what will those reactions look like in reality. This is just basic chemistry, and you show it !
the high speed camera footages of the reactions are fascinating!!
Your vids have come so far 👏
Excellent work 👍
15:21 I’m begging you to make a compilation video of your most visual/trippy reaction shots and put this in it 🤯
Particularly impressive, great work! What an encyclopedic list of reactions.
your videos are amazing, great camera work!
Nice colors again! Thanks!
Dude, i love your content, it is very useful for safety considerations for me as a chemist. Also seeing you doing this dangerous experiments...you have balls of steel!
Right? Lol
*Liquid* ... H2S.
I just can't... And dude here damn sure did, numerous times 🤣
On the mercury nitrate question: The nitrate ions oxidize the mercury sulfide to mercury sulfate, also a white powder.
Fascinating video, excellent work!
Man, this is amazing! Awesome work.
Fantastic work as usual
This is what youtube was meant for.
Awesome video! Sulphur is my favourite chemical element as such I enjoyed it a lot to see reactions where sulphur was formed :D
Yeah it's an interesting creature, just as the element, but has at least one right deadly secret 🤣
Pretty awesome that we got to see liquid hydrogen sulfide for a second time this time with more airtime than the first now I would love to see the same reactions with liquid *hydrogen selenide* (another gas I haven't seen liquefied) by analogy! 👍👍
Great respect, this is how I view the "real" and the most interesting chemistry. Reactions, changes, colors, smoke and fire. Pure passion.
Big up! less talk, more action 😎
Hahahaha, I remember seeing your videos like years ago about B&T Smoke comp.....
The world is a small place I guess 😅
wow!!! I really like the colours... but the 'frozen in time' of a droplet mid splash was my favourite
Your videos are gettinng dengerous day by day. I liked it.
Awesome video like all you do.. can't you do one about potassium ferrate 🤔
Great video!
Seeing the silver react reminded me of some of the earliest photographs.
My guess is, nitrate anion of mercury (II) nitrate re-oxidizes temporarily formed mercury (II) sulfide to colorless mercury (II) sulphate
Way 2 learn inorg! Gr8!
"If we add liquid oxigen to burning..."
Fearless
Realy a best chanell, exotic and rare chemicals-reactions.
There are so meney exotic hypergolic reactions on the chanel that "Ignition" book on rocket fuels dev is shadowed.
That is a real success.
Best regards
I feel compelled to watch the videos posted on this channel, like an H2S sniffing Bluebottle Fly drawn to decomposing cadaver…I just can’t help myself.
Love the music!
Amazing video
Amazing! How interesting the v is. i got one question on the beginning. why you add zr into the mixture of al and s? catalyst? or other reasons?😃
Could you please provide soundtrack list from your video? Especially starting from oxidizers part.
We used to make lots of this, our process was mixing iron filings with sulphur heat the mixture then let cool then drip sulphuric acid on the iron sulphide toi get the rotten eggs smell
The chemistry is beyond awesome but can we talk about the music playlist? Would like it! Thank You!
Given that this is, essentially a substituted chalcogen water and that water and lithium will react to create solvated electrons, could you drop some in the liquid h2s??? Also, if you drop h2s in nh3 it should make an interesting solvent and that might be safe for lithium to go into
I worked in the oilfield and had yo wear H2S gas sensors on our knees. We were trained that if anyone fell over after our sensor alarms went off we were absolutely not to bend down to pick them up. We were to run towards the wind past the guywires. There was entire crews of work over rigs who died and were found picked up in the hole. They told us it was deadly up to 2 miles away at 3' off the ground. I'm curious is this the same gas and is it just more concentrated coming out of the ground? Also we had to change filter pods and those things would ignite in the blink of an eye and we would be shit out of luck if the pods were blocked by something.
just a guess it might be an equilibrium which favours the starting products and can only exist in hydrogen sulfide flow
About the question in the end, the produced NO2/HNO3 vapor quickly oxidizes HgS to HgSO4.
Could you have done a reaction with arsenic that would have resulted in that famous medieval substitute for gold leaf, orpiment, or As2S3?
Hahaha that stuff is about all kindsa friendly all around, no? 🤣
Please make a video like this but about HCN 👍🏾 u would be my hero 😅
Sulfur flames are unreasonably pretty. Why couldn't it be a less stinky element?
The lovely essence of inorganic lab.
Awesome blue flame at 3:10 👏👍
Yess smelly chemistry!!
this is Art
i have a question: why does a solution of Al3+ not buil aluminiumsulfide if we introduce H2S to it?
CZcams advertised "Old Spice". Will this kill the odor?
the H2S was my favourite. love blue flames
Have you seen the sulphur volcanoes like Kawah Ijen? Very rare but some videos on youtube.
@@pattheplanter gotta look that up now. sounds cool!
Our labs have some compounds that can produce H2S if exposed to moisture. It is a terrifying gas and we go to great lengths to stop this, to tell immediately if it has and set off an alarm. Very cool video on a very scary subject! Sulfur compounds always react beautifully.
Why don't chemical supply companies make some safe H2S generators with disposable cartridges? A simple small plastic lined tin can filled with stoichiometric Al - S mixture that wnenever you need some reducing gas you could put one on a stove and just cook it following by taking the lid off and putting the can under some kind of a silicone rubber lid with a gas outlet, a water reservoir and a small water tap to regulate the gas flow. It should be dirt cheap and very easy to manufacture yet it would allow for a lab H2S source that would be completely safe until you properly turn it on and it would have many decades of shelf life!
@@Kirillissimus We just have a risk of H2S production if something goes wrong, we don't actually use it where I work. So, we never actually needed H2S other than to calibrate alarms designed to detect a leak. We can get the gas as a standard mix in a canister, which we need anyway because you need a set concentration to calibrate alarms.
That could work, but I think it may actually be more dangerous. I suspect a lot of companies that need a large supply are okay producing it from loose bulk materials, and there are more economical reactions at scale than this one with Al2S3. For smaller labs, I think it may be safer to just keep any sulfide producing materials under a dry inert atmosphere, and only take what you need for your current production needs. A battery-like design may have excess material after a use that would then need to be discharged, and the gas would need to be scrubbed. It could also build pressure, and you can't just vent H2S to atmosphere. Most importantly though, the production of Al2S3 is extremely exothermic. It gets *hot*, and that is a huge set of hazards on its own!
@@FhtagnCthulhu Dude you mention venting H2S... Yeah like what the hell is happening with the fume hood that can handle that volume without just straight up tossing it?! 🤯
2:21 Metallic fly!
Heh, this brings back memories of one particular lesson at school, when the teacher yells..... who wants to make some stink bombs?
Yep that got our attention, so this was done using Sulphur, Iron Filings, and an acid I can not remember (Any ideas what was used?), with the final ingredient mix to be done outside the fire escape door (Pretty sure the filings / sulphur was heated till mixed, acid added at the end), as the smell was pretty strong, except one of my mates decides to do it inside, and such was the smell, we ended up having to do the rest of the lesson outside, which was fine, as it was a good warm spring day :D
Can you do a video on C3Cl3N3O3?
mercory nitrate does not react with h2s, but instead catalyzes on its surface the decomposition in air of h2s_?
One thing I've learned messing with sulfur is that it doesn't photograph well until it is pure.. that brilliant canary yellow doesn't show until it is nearly completely pure. The sample forming in the nitric acid has to be about *pure*, no?
@10:00 Pretty bubbles.
1:03 Wow 😮😊
Back in the sixties, we made this stuff in HIGH SCHOOL chemistry class! It wasn't until years later that I realized what a bullet we dodged.
Not to mention playing with mercury.
Metallic mercury is a derpy little puppy compared to H2S haha
How do you clean up that toxic mess of Osmium compounds everwhere?
Those flies must've thought you were cooking gourmet food for them lol!
Can you do dimethyl sulfate next?
Me2SO4 wouldn't have many visual properties that would make for an interesting video.
@@joeylawn36111 Sounds like a challenge. I bet with strong enough oxidizer there are some visuals...
The grey appearance on the mercury nitrate might be elemental mercury? Perhaps mercury would spontaneously nitrate in the air if it is finely divided enough and heated, but we never see this normally??
Suggestion: You've done hydrogen sulfide and hydrogen selenide, so You should show hydrogen telluride if you can
Agree. In my youth I foolishly heated powdered aluminum with powdered tellurium and afterwards added a tiny bit of water. Hydrogen Telluride: VILE odor.
I suspect the mercury nitrate oxidises the brown mercury sulphide to a colourless sulphate/sulphite. Though there was a fascinating and very wide range of reactions, I would have liked to have seen the production of iron sulphide, the classic fool's gold, iron pyrites.
🔥🔥🔥🔥
This is also a byproduct of an often undiagnosed cause of Irritable Bowel Syndrome: Small Intestinal Bacterial Overgrowth, or “SIBO”.
H2S video is finally here :D
Sience in action
Alchemy is the future
pour liquid SO2 into liquid H2S
The poisons he handles so you don't have to... He is Chemistry Jesus.
does anybody know why the lilac flame at 6:06 or 6:27 is exactly the same as that of potassium in flame test? does it mean that lilac flame is no longer characteristic to show the presence of potassium anymore?
It feels like a mixture of red and blue flames
@@user-lu9zc8wq8w but to me it's really lilac, a mixture of violet and white, while yours shall be purple in color!
Nice video the last one was best even i am thinking what was happening ,the observations were unexpected. It was a dedicated video on hydrogen sulphide but no kipps apparatus was used. Kipps apparatus may rest in peace 😂😂😂 .
Yeah no kipps apparatus ...another fault identified
@@Exotic_Chem_Lab i didnt tdentify any fault it was just a thing associated with H2S and it was a joke . Its getting too much of yours .
Would like to see reactions with NaK or any other liquid polymetals
Damn, I wanted to find out what the zipper was for.
You know things are gonna get interesting when the KO2 comes out lol

How does H2S behave when properly mixed with liquid oxygen and then being set on fire? 🔥
Solid H2S? That is crystalized death. I don't want to be anywhere near that chemical.
It will be more better if you make a video of Uranium reacting by bromine and nitrogen PLS PLS PLS 😢😢😢😢😢😢😢😢😢😢😢😢😢
