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
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.
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.
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.
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.
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.
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.
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 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
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.
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
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 :)))
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.
"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 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.
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!
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.
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.
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 !
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.
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
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.
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?
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! 👍👍
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??
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
Agree. In my youth I foolishly heated powdered aluminum with powdered tellurium and afterwards added a tiny bit of water. Hydrogen Telluride: VILE odor.
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.
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 😂😂😂 .
