You could've just heated your sulfur with a smashed paraffin candle, heating that makes plenty H2S. Tom showed it in a video, but it is a very very old method.
I know, but that method was extremely messy and required constant (strong) heating. Plus, there was a lot of sulfur vapor that appeared to come off of the mix with the hydrogen sulfide, which I didn't want to deal with, lol.
@@Paonporteur carbon disulfide used to be a common solvent and it's still used, just not as much. It's not that toxic, just be careful with it. There are an awful lot of dangers that have been highly exaggerated in chemistry. Mostly because of insurance companies wanting to avoid lawsuits.
@@Paonporteur This not correct. Yes, carbon disulfide will form, but only at very, very high temperatures. If you don't believe me, read the paper by Bryce and Hinshelwood from 1949. Also, carbon disulfide will only smell nice when it is exceptionally pure (which heating sulfur and carbon together certainly will not produce). I do not believe that you actually performed this experiment!
@@Paonporteur It's not a book, it's from the Journal of the Chemical Society. Your point was that CS2 would form from alkanes and sulfur under these conditions. Read the paper, it does so only in very small amounts. What happens to molten sulfur plus charcoal at >600 °C isn't relevant here. And why are you so concerned with the toxicity of CS2 anyway when H2S is way more toxic?
It would be even easier to drip acid into the polysulfide solution. Btw: do not try to make thioacetone, not even its trimer.... I tried making the trimer on a 10mg scale and apparently a lot of thioacetone was produced as well. Fortunately I didn´t try in a populated area but if you try this at home and in large quantities you will attract a lot of negative attention from your entire town.
I know, but I wanted to avoid possible sulfur dioxide production, even though it may be minimal (seemed worth trying since all I had to do was react the acid with aluminum foil). I'd be very interested to hear your experiences with thioacetone, including the smell. I'm hell-bent on trying it myself in an unpopulated area, and I'd love to know what I'm getting myself into, lol. I'll probably contact you over Discord to ask.
If it was a weak enough acid (for example the aluminum salt method you used in this video), it would still sufficiently reduce SO2 concentration to affect the reaction with thioacetone.
Even though paraffins are flammable, the carbon and hydrogen bonds are so strong that only chlorine and oxygen, which are safe to transport, can easily burn paraffins. Some high valence metal sulfides can form the desired compound when reduced with hydrogen to form lower valence metal sulfides. However, it smells very bad.
In regard to aluminum chloride solution, aluminum 1100 alloy welding rods which is essentially pure aluminum would probably give you less “junk” to filter out.
Good suggestion, but my blender would burn out before the aluminum foil ever got fine enough to burn, so as I mentioned in the video, this method wouldn't work for me.
@@makeomengreatagain you're welcome to try, but you'd probably be there for as long or longer than a ball mill (a day or more of continuous grinding for any meaningful yield). I'm actually considering building a ball mill to grind my own metal powder, but it might be a while before that's done. I'll definitely make it into a video tho, because ball mills can be stupid- expensive if bought, and they are potentially really useful!
Copper powder is easy to make (CuSO4 & reducing agent like vitamin-C) and should also work fine. Maybe even gallium (no need to make powder!) would work...
@@27.minhquangvo76 You might be right. If you use HCl then I expect it would react like this: CuS + 2 HCl --> CuCl2 + H2S, but in case of H2SO4 there would not be reaction. Not sure. I guess there is equilibrium for it, but certainly not the best method.
Ok question time? Once ive synthesized my hydrogen sulfide and bottle it, is it contents under pressure? Like after 3 days im not going to have the living shit scared out of me because pressure was building up in the reagent bottle, and BOOM 3am in the morning?
I have seen in a safety video from a Middle East-based natural gas company that during a H2S exposure, water is not allowed for washing on site, since H2S gas combines with water to form sulfuric acid, which is equally as corrosive as the gas. Here is the video clip: ua-cam.com/video/zl7VTtCpw9E/v-deo.htmlsi=2Eogmru4tTFYmWVe
Hydrogen sulfide H2S an extremly deadly killer. On ships the water oil separators/Bilge water treatment plants , are realy silent killers. Water and waste oil in a confined space quite a deadly combination , H2S is quite a killer gas .
Nope, iron sulfate doesn't react with HCl. Iron sulfide does though, and it will produce hydrogen sulfide, but I didn't have the stuff to make it at the time.
@@TeslaWorkshop Any FeS would work (in fact, most metal sulfides will work), but iron sulfate is FeSO4 or Fe2(SO4)3. So if HCl were a strong enough acid to act upon iron sulfate, it would produce sulfuric acid (H2SO4) instead of hydrosulfuric acid (H2S, also known as hydrogen sulfide).
is there any byproduct of making hydrogen besides 2H 1O? I remember one day smelling the hydrogen gas that was left inside my Hydrogen generator and it smelled very strong and stung a little to this day I am curious what it could have been.
Nice. 2:09 There are not a lot chemistry UA-camrs who are already answering my questions before I've asked them. 👍 I hope the FBI will not come to your house to force you to take this video down like they did to the Backyard scientist... 😱 Please buy a gas mask for such future projects and perform experiments with H2S only completely outdoors (not even in the half-open garage). H2S is nearly as toxic as HCN! I produce H2S with the paraffin methode only microscale with a peace of glass tubing which I had closed at one end by melting it in the blow torch flame. I just discard the tube afterwards because it's impossible to clean it without much worse solvents (CS2). Two spatula tips each of sulfur and paraffin are enough then to make 100 ml of a saturated H2S-solution.
@@pew8208 You forgot to consider the exposure duration: HCN: 100-200 ppm lethal in 30-60 minutes H2S: 100 ppm lethal in less than 1 hour. That's not so far away from each other... Only in even higher concentrations HCN is faster deadly than H2S. More people survive H2S because the warning effect of the smell sets in much earlier. But once unconscious you wouldn't have low chances with both... I don't even know if I can smell HCN at all. So if I had to choose which one to work with I would indeed take H2S. That's why I don't handle any cyanides. In so far you are right. 🙂
@@experimental_chemistry yep can can indeed smell HCN but only at very and I mean very low concentrations in fact so low that it's not even that toxic anymore and as the concentration ramps up it's lights out before you have the chance to realise similarly H2S is toxic but it can be easily cured without the need for a amul nitrate solution like for treatment of cyanide poisoning It's been researched that if you give a extremely high exposure of h2s gas to the point where the person has fainted and is unconscious and then give em fresh air boom without any fancy thing back to life again as normal but the thing with h2s is that when the conc rises it causes a severe olfactory fatigue and u can't smell it any more so you might think u are getting fresh air but in fact the concentration has risen. Ohh and HCN gas has a really nice nutty almond smell to it it's unusually pleasant(at low conc)
I'm not entirely sure, I suppose you might lose some H2S but I can't say for sure! Aeration with ozonated oxygen would probably work the best though, as ozone is frequently used to purify water, and it should easily oxidize the H2S to water and insoluble/non-toxic elemental sulfur.
But what about the solid left in the filter funnel? Is that not aluminium trichloride? Should I not wash it and use this compound sometimes down the road?
@LabCoatz_Science thank you for getting back to me, I had a heated argument with a colleague about this and I told him just watch the video!!! I'm so glad we have chemists like you who give insight to a lot of us who sometimes come to a conundrum with our experiments and because guys like you do these experiments with experience, it's refreshing to know I'm a couple clicks away from a fresh new outlook at my fork in the road. Happy holidays, and keep doing your stuff! It's appreciated 😌
This dude don't have hydrogen cyanine.. lol. Dunning- Kruger. He knows the names of 2 deadly compounds but nothing about chemistry. Must be twice as deadly if its got 2 killers...😂
If you're talking about dissolving the H2S in water, you'd need to do the reaction in a sealed container with a hose and bubble the gas through water. But if you're thinking about drinking this "sulfur water" or using it on your body, don't even think about it. As stated in the warning, this gas is extremely poisonous: if even 0.1% of the air you breath is H2S, you could immediately collapse and die. Most of the sulfur in "sulfur water" comes from dissolved sulfate minerals, not H2S.
Lol, well, you're chemistry teacher is very very wrong. This stuff is easily more toxic than cyanide, and according to this official website, a single breath with more than 0.2% in air (2000 ppm) can be "immediately deadly": www.osha.gov/hydrogen-sulfide/hazards There are also multiple stories about people who died from this stuff, and another UA-camr (TheBackyardScientist) even got visited by the FBI for making a video that showed how to make one of its precursors (aluminum sulfide)...apparently terrorists were interested in using it! The good news is as long as you can smell it, you're usually fine for short periods. Once the concentration gets above roughly 100 ppm though, you start to loss your ability to smell it, and the toxicity becomes more significant.
I work at an oil refinery, can confirm that hydrogen sulfide is extremely dangerous. We are required to wear monitors constantly that alert us of the toxic gas in the air.
Thanks man! I knew about the wax-sulfur method, but it is extremely messy and requires constant heating. The thought of cleaning that much wax and sulfur off of my glassware was a strong enough deterrent for me, lol.
To make the stinkiest substance on Earth, of course! It was for my thioacetone synthesis, like I mentioned in the video. I used it all up back in July for that project.
