This is not a physical dissolution, but rather a chemical reaction between potassium hydroxide and sulphur, giving potassium polysulphides. When you add winegar, the acetic acid contained in it causes the decomposition of the as-prepared polysulphides, giving off gaseous hydrogen sulphide, potassium acetate and finely divided sulphur suspended in the liquid. Be careful, as gaseous hydrogen sulphide is an insidious poison and you should operate outdoor when you add winegar, absolutely avoiding breathing the released gas, smelling of rotten eggs.
Maybe just try some hydrocarbons to dissolve it. I think that it may be a tinnyyyyy litttlllleeee bit better than wasting a bunch of alkali metal hydroxides just for waste cleanup. A stirbar on the highest setting and some mineral oil is all you need.
We use the so called wettable sulfur to spray vineyards so we are trying to find a cheaper alternative to commercial products. Do you think (no compromise, just a quick opinion) dissolving sulfur as shown here could be a valid alternative? or it must be micronized and added some other dispersant to achieve the 1-2% sulfur solution used to spray?
Dear Raven, thanks for sharing the video, you really solved my problem. I just wanted to query whether we can mixed the final solution with water. Thanks is advance.
Thank you, "Sulfur dissolves in Alki hydroxides" that's the key phrase I wanted to hear. Do you think that would work as a dental rinse to remove sulfur deposits?
I personally wouldn't put this stuff anywhere near my mouth, since it draws fats out of organic matter, and reacts to form soap. I have seen few horrifying pictures of some accidents and they weren't pretty. Using alkaline hydroxide solutions to remove sulfur from lab equipment or things, that aren't prone to its dissolving properties, should in my opinion be okay, but testing should still be performed to make sure the solution won't damage the work piece.
Okay, good to know caution, I was wondering if it'd make a mouth soapy, thank you very much. I'll keep this in mind. Maybe there is a safe dilution. I bet the smell of the lab equipment must get quite repulsive when dealing with sulfur. But I guess that's of the least concerns comparably to health & safety. Maybe if we can smell it then we need to contain it & the reactions better.
I bet your local dentist could do the job easier and safer ways, and give guarantee that the job is done by professionals. As you can see, the reaction needs also heat to dissolve anything, so I guess boiling hot alkaline metal hydroxide solution would be ill advisable at best, and could ruin your mouth very easily. Actually in labs around the world and my work area, the reactions are in fume hoods or similar well ventilated areas. Hydrogen sulfide is a chemical that even in the smallest quantities will be noticeable. It's part of what makes farts smell.
Does it need to be boiled to react? To be honest, I've spoke with them. Initially they seemed less informed about existing alternatives than I hoped. And they opposite of guaranteed results with what they have. Carefull not to get to comfy with fume hoods, they can fail or be missused. I think a fume hood should be running simply as a backup, not a primary; At least when dealing with hazardous||dangerous fumes. Plus fart and rotten egg smell might not be very desirable, even in small detectable quantities.
When I was younger I thought the same, but then if I remember correctly Nurdrage came in to the picture, and I learned a lot :D But I'm glad I could teach you something! :D
I'm not sure if I know what kind of sulfur is even used in gardens, but if it has to be elemental sulfur, it won't dissolve in water. If it is in a salt form, then it is possible, but what salt is then the question. If it's in powder form, maybe an air spray, the kind they use to apply powder paint, could work?
@@PlanetHell67 It isnt, but in small amounts you can do it and it could be even beneficial, bc sulphur occurs naturally in our bodies. Otherwise, wash the vegetables before eating and you"l be safe
@@RavenFly1232 Hi Raven What would happen if one mixed the powders of Sulphur and Potassium hydroxide and vinegar without heating , would it still have a reaction of the smell ?
@@raubextrainingcentre5459 Maybe. I'd imagine the acid reacting with the base first, and then the leftover base would react with sulfur and no smell would be produced. Then again, there might be simultaneous reactions happening, but I don't believe mixing everything together would do anything, and without heating the reaction between the base and the sulfur would be extremely slow.
@@RavenFly1232 reason I'm asking . I'm trying to figure out what is being used in a stink bomb bag ruclips.net/video/5gMAIgzi85w/видео.html I know they uses vinegar but what powder are they using
I need to dissolve surfur to get the granules out to make sulfur cream is this doable the sulfur I got is gritty and doesn't dissolve in oil to make sulfur cream thanks
I'd recommend against using this method to do anything that is going to be applied on living tissue. The hydroxide used is extremely corrosive, and will probably strip the skin off the flesh if put on. Best method I think to make a suspension of sulfur, is to get a small coffee grinder, and grind the granules into a fine powder (do this outside, wear a mask, you most definitely don't want to breathe in the dust), and then make a suspension. Or if you need to extract the sulfur, you can recrystallize using toluene or xylenes, and then extract the crystals of sulfur.
Hi.There is some liquid Sulfur fertilizer on the market which have about 15-19 % sulfur on them and there are other type which have about 80-90 percent of sulfur (suspension).Is this liquid sulfur solution ?And can be used as fertilizer?thanks
I actually don't know. In general, to know what some product contains, safety datasheets, or back labels are a must, and without knowing specific product in question, it is really hard to know. I live in a country, where most everything is heavily regulated (well, at least consumer products), so finding what a product contains is easy. The harder part is to find OTC chemicals that are pure enough to begin with. From what I know, sulfur for plants can be pure, but often is part of a larger molecule, so separation may not be feasible.
Is sulphur dangerous? And should i be wary of it? I know sulphur on its own in its true form is harmless. However was talked into buying it to treat chicken mites by a salesman. Have noticed that the sulphur residue has reacted with my eyes causing an annoying stinging sensation. This was also after washing my hands. Also managed to get some sulphur dust on my clothes while aplying it to the chickens. Clothes now smell like rotten eggs after a few days. Needless to say i wont be using it again. Is the sulphur dangerous in a coup if it comes into contact with water?
I'm not able to give medical advice, but I would strongly recommend reading the MSDS and contacting your doctor for the eye irritation if it continues, after washing your eyes with care to avoid anything harmful happening. Sulfur is of low toxicity to humans, but if ingested, inhaled or it is in contact with skin or eyes it may cause irritation. Probably the best way of getting rid of sulfur is to wash the clothes a couple of times. If it is in fine powdery form, it might be harder to get rid of as sulfur particles can get lodged between the fibers. Also sulfur by itself doesn't react or dissolve in water, but bacteria etc. could use it to create some harmful or smelly compounds. When it comes to chicken, I have no idea about sulfur toxicity, the MSDS and instruction manual could be of use, but most probably as long as the chicken aren't exposed to too high concentrations of sulfur, and as the product is intended to be used with chicken, I assume that the chicken are going to be fine. Anyways, say hello to your chicken from me, they are one of my favorite animals!
We can melt it, a bit over 100C isn't that high, so that's doable. In this video I didn't make liquid sulfur, I reacted it with KOH to produce salts that can dissolve in water. If you mean have some sulfur compound that can dissolve in a solvent, then there are plenty of options. Or find a solvent that can dissolve sulfur, like toluene at high temperatures.
I had no idea that sulfur could be part of shampoo. So without knowledge what compound the sulfur is and in what concentration, I can't tell even in theory how to do that. And I also assume that you are intending to use it on yourself, in that case I'd strongly recommend just buying the stuff.
Medical stuff is not my strong suite, I have no formal training nor have I read enough about the field to approach this question in any deeper way. The solution itself is probably poisonous, and if ingested, or injected, or even applied topically would cause definite harm due the caustic solution, and probably everything else in there. There may be some limited use in syntheses of other chemicals that may be useful in some way, but as is the solution is definitely not healthy. I believe you are looking some organosulfur compounds like certain amino acids etc. But for anything medicinal, you should consult someone more qualified.
@@althafibrahim5639 I'm not sure if sulfur solution that isn't somehow toxic exists. A quick google search indicates, that most of these sulfur products are some sort of emulsions or suspensions, so maybe you should try to go that route? Thick enough cream and fine enough sulfur mixed well together maybe? I am no medical professional by any stretch, so I'd recommend consulting some professional before using any self made ointments on oneself.
When I was a kid, I liked chemistry and I also liked whatever made a loud bang, so the first chemical reaction I did by myself was putting aluminium foil in a bottle with drain opener (alkaline metal hydroxide) and sealed the bottle. After that I wanted to do much more, so I started collecting laboratory glass and chemicals, and over time I've learned how to distill stuff etc. Also channels like NurdRage and NileRed on RUclips were a great resource. If you'd like something that smells good, some esterification reactions produce very nice smells, like fruit smells.

Absolutely. There should be a warning in the video.
If you use stronger acid will it not allow the sulfur to precipitate so it will all convert into HS2?
Interesting video, thanks.
Thanks I just managed to recover a conical flask that had melted sulphur stuck on the bottom... it's now clean again!
Great to hear!
have you considered trying Sodium hydroxide and water
