- In this video, I'll be demonstrating three methods to produce sulfur dioxide gas. Sulfur dioxide, while undesirable on its own due to its toxicity and environmental impact, serves as a crucial precursor for various chemical processes, including the production of sulfuric acid. These methods have been showcased in previous videos, but I've compiled them here for easy reference.
Method 1: Burning Sulfur
The most cost-effective approach involves burning sulfur. Elemental sulfur, often used in gardening and pest control, is readily available. By burning it and capturing the resulting sulfur dioxide, we can utilize it for various reactions. A gas capture setup is essential, comprising a metal funnel over the burning sulfur, connected to a coil of copper tubing to cool the gas, and finally linked to a reaction flask using plastic tubing. Vacuum assistance is used to pull the gas into the apparatus, eliminating the need for a sealed combustion chamber.

Method 2: Sulfuric Acid Decomposition
This method involves adding elemental sulfur to concentrated sulfuric acid within a sealed distillation setup. The sulfuric acid decomposes the sulfur to produce sulfur dioxide and water. While this approach yields relatively pure sulfur dioxide, it is slow and inefficient for amateur chemists. Moreover, the risk of dealing with boiling hot sulfuric acid makes it impractical for most.
Method 3: Sodium Metabisulfite Acidification
The most convenient yet costly method involves sodium metabisulfite and hydrochloric acid. A generator is set up with water, sodium metabisulfite, and hydrochloric acid. Upon opening a valve, the hydrochloric acid reacts with the sodium metabisulfite to instantly produce sulfur dioxide gas. This method offers convenience, immediate gas production, and purity, making it preferable for many applications. Sodium metabisulfite, found online and used in food preservation, is readily available for purchase.
In summary, these three methods provide options for generating sulfur dioxide gas, each with its advantages and drawbacks. The choice of method depends on factors like cost, convenience, purity, and safety considerations for specific applications.

Granted, it's a simple video, but I'm trying some strange stuff with sulfur dioxide and if it works out I'll make a cool video with it.
It doesn't matter what you post or why you post it
I will always be here to watch it
Love these simpler videos for beginners.very thorough as always.thanks for your videos!
Could you use platinum to make sulfur trioxide now that you have made SO2 ?
Have you tried to use bisulfate with heating to produce SO2 from metabissulfite?
the simple videos are the easiest to under stand for the non-chemist types 😉
This brings back memories... Or nightmare...
When I was a kid I tried making my own concentrated sulphuric acid with the sulfur burning method, a pound of powdered sulphur, melted in a coffee can , being blasted with a propane torch, i didn't have enough copper tubing so used some vinyl, the asperator was held together with tape , not enough vacuum, the vinyl melted , the stand I had the coffee can on collapsed , everything was burning, in an unventilated basement , I barely made it out alive, lucky I didn't burn the house down. I'll never forget struggling to breathe as I collapsed in the backyard with my bronchial tubes nearly completely swollen shut unable to do anything !
Every bit of silver in the house was damaged, some to the point of pitting.
When my parents felt it was safe to come back home a week later, first thing my mom did was toss my chemistry set out.
I was about 11 , give or take a year... (Tween years)
oh shit just experienced that on a small scale with 14g burning sulfur but quickly reacted, put the can out the window and closed it, quickly got a metal plate from the adjacent room and put the fire out (it was too big to blow out). closed of the room and didnt enter it for 2 days now. i did get one or two good whifs of it but i think im fine
sulfur dioxide without a proper setup is no joke
Damn son 😂 . . . . We all do dumb things, I once used a firecracker to get our family dog out of the bathroom, except I chose to put the firecracker in the toilet and it blew the underside of the john out.
The dog was even more reluctant to come out of the shower after that 😂
I was around the same age, yours is more impressive though from a smart kid perspective, at least you were doing something productive, I was just trying to get the dog out of the bathroom to take a shit alone 😂.
@@jordanhess2061 well my ultimate goal was to create a nitration mix, and make my own nitroglycerin ...
...Things could have been worse...
I did make NI3 (touch powder) , but the little crystals exploded like small firecrackers just from starting to dry so I panicked and washed it down the drain... For the next day pipes were rattling, you can hear things popping in the sewers... Didn't tell my parents what those noises were coming from, they thought it was something from the town...

Yeah bro we saw the video too. We don't need your book report on it
@@jogandsp Some people might wish to actually use this video as a reference while doing amateur lab work, so having a quick resource in the comments makes the information more accessible. Just because you find no utility in such a comment doesn't mean it's useless.
@@theKashConnoisseur the video is 8 minutes long. If they need to know the information they can just watch it.
@@jogandsp or they can save 7 minutes and 45 seconds by referencing this comment and going right to the info they need. You're entitled to your opinion, but know that it's ill informed and that nobody agrees with you.
I've seen you on a few others of his videos I think. You're doin great work keep it up
NurdRage please keep posting we've missed you !
I liked it and would enjoy more informative videos about lab equipment and procedures.
Great video thanks for sharing
When you said burning sulphur for pests... yeah, some of the guys here take home some sulphur and burn it in a pot in the shed, no more spiders lol. Don't do too much, things might get rusty...
I'm interested in methods of turning calcium sulfate minerals (Gypsum, plaster of paris, etc.) into sulfuric acid via evolution of sulfur dioxide. I've become interested in this for SHtF/survivalist scenarios; sulfate minerals are incredibly common the world over, where as elemental sulfur is comparably rare. My understanding is that merely mixing such feed stock with high silica minerals (shale, mud stone) and getting it hot enough achieves the goal. I'd be interested in a NurdRage take on the process.
Have you considered looking into the DMS/DMSO process and the different ways SO2 can be produced from organosulfurs and reacted with them (IE via methylation/hydrogenation/oxidation) to form other useful compounds?
Reading into it recently myself I find it an interesting set of ways to use these waste products to produce more useful compounds.
organic sulfur compounds are one of a hell to work with, so I wouldn't use them to make just SO2
@@dimaminiailo3723Lot of chemicals are rough on lab equipment and dangerous to work with.
I was just pointing out an interesting 'not so frequently used' approach that is possible: which I think is important to be aware of for DIY purposes.
Not just about creating 1 chem for use; but assessing possibility of what side products may result (that are also useful), and/or may be able to be reacted with otherwise waste products you'd have to dispose of/etc.
@@djdrack4681 if you're talking about SO2 from DMSO, that's utterly useless even if it were possible
Tanks so much❤️🌹
Nurdrage, can you make a video about how to make SO3 (contact process) on a small scale, please?
Most interesting part is making the catalyst. It is non-trivial.
The man is back
Cool gonna follow this tutorial and leave the URL to this video on a note nearby just in case.
Could you use platinum to make sulfur trioxide now that you have made SO2 ?
Great video Nurdrage! Thanks, in our smelting process, they're using diesel to cook the concentrates, this is producing a nox gas in the sulphuric acid. Could you some how explain how a company who treats a sulphuric acid which contains nox? This gas is produced when we dilute the acid, which I do when regenerating a Cation unit (part of the process to make demin water to recharge the resins) I know nox is pretty bad, we do have gas monitors for it as we can't smell it. Thanks again for your videos.
Yay, making cautious stuff again!
Metabisulfite method for small quantities of high purity. Burning method for large quantities. A pair of good videos would be making the vanadium catalyst and then making sulfur trioxide. Key step is purifying the burning sulfur dioxide to remove water and sulfur and sulfuric acid which damage the catalyst.
Making sulfuric acid from sulfur trioxide is also non-trivial. The first of two methods I have tried are dissolving in concentrated sulfuric acid to make fuming acid then diluting.
The second is putting the sulfur trioxide in a closed setup with an appropriate amount of water in two cups. Everything gets coated with sulfuric acid, but you get 98% acid where you had sulfur trioxide. The cheapest way to set this up is a flask with a vacuum adapter and stopper. Use ptfe tubing to attach the two pairs. Since it takes a long time dedicated glassware is ideal. Some gas line tubing has ptfe core which is available at auto parts stores for reasonsble prices.
If you have a distillation set up without a condensor you can use that. It takes a bit but it works and everything is contained. But it will be out of use while this is happening.
Two commercial products, 'Iron Out' and 'Stump Out' are cheap sources of sodium metabisulfite and may be substituted for the more expensive reagent grade material. Both may be found at any big box home improvement store.
Here in Germany sodium bisulfite and hydrochloric acid are very easy and cheap to obtain (6 Euros for a litre of technical grade HCl from the hardwarestore and 11 Euros for a kilogram of bisulfite online). The only problem is the storage: both substances need to be stored in bottles under tightly sealing teflon-coated caps, otherwise the escaping gases will corrode everything made of metal and located in the same room.
The use of conc. sulfuric acid is completely forbidden for private individuals in the EU.
Out of curiosity. What is your fume hood setup, and what do you have for a gas mask if you wear one?
Its hard to get ahold of good quality full-size hoods w/ sides/etc due to size and transport. So curious if you have a more DIY setup.
Yeaaaah now we we can make sulfuric acid
Cool
Sodium Metabisulfite vs Potassium Metabisulfite?
I often use the latter in brewing (Campden powder/tablets).
Yup homebrew supply shops
Home Depot sells sodium metabisulfite in the form of Bonide Stump Remover.
I woke up this morning wondering how to generate sulphur dioxide gas. Was pondering if eating several plates of beans would do the job.
Maybe of I eat beans and eggs.
Didn't know about the H2SO4 version, but like you say it's kinda got more issues than it's worth
Is the comproportionation S + 2 SO3 -> 3SO2 viable/easy? If yes, then for some SO2-reduction reactions it may be viable to set up SO2 regeneration loop, where you use SO2 + yourstuff -> yourstuffreduced + SO3 in your main reactor and regen SO3 back to SO2 in auxiliary regen reactor
SO2 is an efficient reducing agent in water solution, not by itself, so you product will be sulfuric acid. anyway, SO2 is very cheap for most people and thus that method is not very convenient
NerdRage posts a video, I click simple as that.
2H2S+SO2=2H2O+3S. in gas phase it is nice reaction one can see formation of yellow sulphur 'smoke'. I wonder what happens when you mix liquid SO2 and liquid H2S .
I would like to add Smelting of Gold Concentrates Containing Sulphides (as in almost all gold concentrates).
If you have ever done Roasting you know there are clouds of SO2 gas that stream off for about 30 minutes.
Pass those fumes through a simple water spray box and you'll make dilute H2SO4.
Boil the acid until it becomes syrupy and enjoy the spatter wounds on your face. Fun! :D
SO2 + H2O makes H2SO3 not H2SO4
You still need V2O5 to catalyze the SO2 to SO3
It should be possible to use the Sulfur-burning method also without vacuumpump, if the S is burnt inside a closed container, into that just enough air is pumped carefully, so the flame does not go out.
Question: is potassium metabisulfite also an option instead od the sodium metabisulfite?
yep! works just fine. But Sodium metabisulfite tends to be cheaper and easier to get, so might as well go with that.
@@NurdRage thanks for the reply and helping out! Its easier for me to get potassium one for some reason lol.
Wood charcoal can be used instead of sulfur, it's more convenient being non-volatile. SO2 is somewhat contaminated with CO and CO2, but for most purposes it's not a drastic difference
Won't the hot SO2 erode the copper tubing into copper sulfate? Especially if there is atmospheric oxygen available?
it shouldnt, SO2 doesnt readily react with copper, neither does H2SO4, if it does at all it will probably passivate.
Now what would one do with SO2
now do one for SO3 :)
What about putting the sulfur candle in sealed chamber & feeding in oxygen from oxygen concentrator? Will the reaction get violent? Can the rate be controlled by the oxygen feed rate?
It would work just fine. The issue is that making one tends to be a little more complicated than the vacuum method because you have to make it air tight and capable of withstanding the high temperature of burning sulfur. It can be done, but a vacuum based system doesn't need good sealing, in fact it can be very leaky and still work.
My question focuses on the use of pure O2 versus air. You could still use vacuum, but flood by leaky means O2 around the funnel. Will the reaction become violent or explode, sending molten sulfur everywhere?
The object is to reduce the amount of gas delivered for a given amount of SO2, because for most gas deliveries like this, most of it doesn't get absorbed in the target flask & spews about, wasting product & polluting the environment. If ALL the gas was SO2, then there would be little need for venting the reaction vessel, so SO2 could be regulated for "no output" from the vent. Neighbor's silverware would remain untarnished.
If you're going to go through the trouble of making pure o2 and a sealed container then you may be better off using the sulfuric acid or metabisulfite methods. Less work for pure SO2
r @NurdRage I already have the concentrator. I don't have sulfuric acid. What I want to know is if pure oxygen will make sulfur candle dangerous.
@@bpark10001Concentrated oxygen and combustion is always dangerous. Any combustion reaction will get more violent when you increase the concentration of the oxidizer. Rate control would probably be difficult. If you can't guarantee that all of the oxygen you add will first react with the sulfur, then increasing the flow at times might increase the reaction rate, or it might just mean the oxygen you add will pass through into the exhaust with the SO2. It's probably not impossible, but that's not an experiment I'd want done anywhere near me.
If your concern is about waste SO2 escaping and harming metal objects, maybe you could make a scrubber where you bubble the exhaust from the vacuum pump through some sodium hydroxide dissolved in water or something similar. On the plus side, this would make sodium metabisulfite, which you could use to generate SO2 gas on demand in a more controlled manner.
Liquid SO2 is a polar solvent like DMSO.
What year is it?
Some one has the link for the video teaching how to assembly the vacuum pump system.
good point! i forgot about that, i added it to the video description.
@@NurdRage thx man.
Can someone explain to me the method of sulfuric acid to produce sulfur dioxide? I don't know English (I use a translator).
sulfur and boiling H2SO4 give SO2 and H2O, H2O is distilled off, SO2 is your desired gas
@@dimaminiailo3723 thank you
Generally I find that the extra tubing gives you a smoother toke
I might be wrong but burning sulfur produces a blue flame with UV no ? If I'm right, do not look at the flame directly. Someone knows more about it ?
Kind of reminds me of method to make hydrogen sulfide by boiling sulfur in paraffin
Who else is watching the video over and over and viewing the ads so nurdrage gets money
First
Watching your videos since I was a school student
Lmao get ducked
I like ducks : 3
Condense SO2 to liquid SO2. Organic reaction medium, used in long life Lithium/thionyl chloride batteries. SO2 dissolves HCl gas.
Why would you dissolve HCl gas into a dangerous medium when water does it so easily?
I've never heard of a battery that uses liquid SO2 for an electrolyte, can you tell me more, like is it only low temperature or high pressure? What safely holds it? What kind of thiols? Etc.

There is another way to make sulfur dioxide. It involves eating a lot of beans… 😂

Sodium Bisulfite plus Sodium Bisulfate, cheap.
And of course you can use CuSO4 instead of H2SO4
Oh yeah, SMB in acid is really harsh, I normally like the smell of chemicals but even tiny amounts of SO2 makes me cough my lungs up...
Also works for clearing trenches, should you be dealing with a nasty invader.
I don’t need lab equipment to make sulphur gas. 💨
