Hey bro, Since i don't see anyone commenting, metabisulfite is used in homebrewing for sanitation. You make a solution and wash everything with it and it helps disinfect everything. When making cider or wine you also add it to the fresh-pressed juice to prevent wild yeast from taking hold and fermenting the juice instead of your preferred brewing yeast strain. Iv been homebrewing for a few years now :)

Home brewer here. While I don't use it in my own brews Sodium Metabisulfite is a stabalizing agent, if is toxic to the micro-organism used to turn sugar into alchohol (yeast). The idea is that you brew something dry (no remaining sugar) to the alchohol content you want and then let it sit over night with a small amount of sodium metabisulfite then syphon the brew off and back sweeten it. This way you are not reactivating any yeasts and not potentially causing a bottle to explode later (yeasts byproducts are ethenol and carbon dioxide)

you could always convert it entirely to bromine monochloride and ampule some of that!

Love your honesty.

Excellently done, m8

I love this channel.

A new method - the Australian method. For the record I would like to see you doing the Australian method as in drinking a lot throughout the process.

Sodium metabisulfite is commonly used in two concentrations (~5g/L and ~1g/L). The high concentration solution is sufficient to sterilize equipment and does not require rinsing, so there is no risk of contamination from rinse water/tools. The low concentration solution is enough to kill/inhibit wild yeast and many bacteria, but cultured yeasts can survive it. Wine snobs will say that only potassium metabisulfite is used in this way, but they'll also pretend that they can taste the difference between identical wines poured out of differently shaped bottles. This solution is actually made in the must (fruit mix) that will be turned into wine. I'm not sure if brewers use it, but it's commonly used in wine making. ETA: For those in the comments saying that it's not used in actual wine - it is. Campden tablets are either sodium or potassium metabisulfite.

Mate, Aussie here. I'm in Western Australia. You can buy spa bromine tablets in any pool supplies store here. I have dropped them into a 3l flask with toluene and with a reflux condenser topped with a distillation condenser into a collection flask. You need a lot of condensing surface for what is coming. Then heat the lot slowly, until the reaction starts. It takes off with an exothermic whoosh but if you can keep the beast under control, you quickly end up with a heap of benzyl bromide and also a heap of pure bromine. I was after benzyl bromide, experimenting with halogenated hydrocarbons, but ended up collecting a liter of bromine too. It is a nasty lachrymator. If you lose control, you end up with a lab covered in Benzyl bromide and hydrobromic acid among other things.

Working outdoors in the rain with electricity does add to the challenge of success. Still you got Br2 out of it. Is there any way to separate out the Cl or is it like an azeotrope?

Sodium metabisulfite and more commonly potassium metabisulfite (kms) is used in wine for sterilization (when mixed with citric and water cause of some fun equilibrium) and also just added straight to wine for microbial control and oxidation control. As far as I know, for metabisulfites most places use potassium based cause the sodium one at wine pH causes some unpleasant salts to form and precipitate. I imagine it's similar for beer

Sodium metabisulphite is used as a disinfectant in brewing. Its an easy and effective way to kill mold/fungus spores and wild yeast. its easy to wash out and doesn't leave any residue like a lot of detergents.

I have gotten pure Bromine out of those tablets before. I can't recall off hand what I did to bind the chlorine but I was sure it was all trapped in the reaction flask. I wasn't adding sodium metabisulfite though, I was reacting the tablets with hydrocarbons, like Toluene. The bromine was a biproduct really but I duly collected it since there was so much and it is a pretty element. I like it more than chlorine. My favorite halogen. 😍

Wait, how do you get only 30-ish grams of bromine from 175 g BCDMH ? To my understanding, bromine makes up about 33 % of its molecular weight, meaning the theoretical yield of bromine would be about 175 * 0.33 = 58 g? Also, if you used somewhat stochiometric amounts of the reducing agent, and therefore its availability was the limiting factor in this reaction, the formation of chlorine instead of (and not in addition to) bromine would only lower the total mass of the product, not increase it. Am I being stupid?

Sodium metabisulphite or the potassium version mostly is used for preserving homemade jams and fruit syrups.

Sterility is very important there One extra thing, can you reflux the bromine to get rid of the BrCl with a 10C water bath?

Could you reflux the bromine to get rid of the chlorine?

They do use sodium metabisulfite for sterilizing their equipment. But they don't add sulfites directly to the wine, only sulfur dioxide. (I guess so that it doesn't mess too much with the pH and salinity?) The latter is done to kill unwanted bacteria that could oxidize it and start making acetic acid. (A process called Maderization, usually unwantd except in a select few cases.) The other reason is to help stop the fermentation early, before all the sugar is consumed, so that the wine can remain a little sweet. (In which case they often also use it in conjunction with potassium sorbate.) That is mostly done for white wines, as those grape varieties usually tend to have less sugar than the ones used for red wine. With the latter, you can often leave the fermentation go to term: with enough sugar, and the right yeast strain, it will spontaneously stop when the alcoholic degree becomes too high for the yeast, leaving some sweetness still in the wine. White wines also tend to taste better with a little more sweetness than red wines. It's also frowned upon as a way of making cheap but crappy wine: less fermentation means less fermentation products (alcohol, but also a lot of complex molecules made by the yeast, which contribute to the wine's flavor). So it's basically the same as having a more dilute wine, as if it were cut with water. And in addition to that, it also kills a bunch of anaerobic bacteria responsible for the wine's aging, so they simply don't age well. A better winemaking technique is to grow grapes in places where they get more sunlight (in the northern hemisphere, south facing slopes are ideal, north facing in the southern hemisphere), and/or let them mature a little longer before the harvest. But that also implies more expensive plots of land and lower harvest yield, so it's done for the better, more expensive wines. Except in Switzerland, where their local wine costs an arm and a leg, but still tastes like sex in a canoe: f*cking close to water! (They just don't get much sunlight I guess. But that doesn't excuse the price! I could buy much better Chilean wine there at half the price of the local ones...)

Sodium metabisulfate is used to sterilize your beer or wine must to kill bad yeast before you add the good yeast. It is also used at the end to preserve the wine for aging, other wise wine shouldn't be aged because it could go bad. but in beer its not used at the end because you add a bit of sugar to the bottle to promote yeast growth and if you add the sodium metabisulfate it will kill the yeast.

It's more commonly used to kill wild yeasts in wine must and beer wort, as well as a source of sulfites in finished wines as a preservative. Other stuff (like Star San) are used as disinfectants due to having more desirable properties. I do a bit of homebrewing and I use metabisulfite to protect my finished meads from oxygen.

Is there any effective difference between Bromine Chloride and Chlorine Bromide?

There is no such thing as Bromine Chloride. It isn't possible. They are both halogens, will both react with similar things. Chlorine is more reactive than Bromine, and when the two meet, Chlorine liberates Bromine as free atoms in these pool and spa products.

Buy a outdoors overhang tarp with the legs on it so you can do chemical reactions outside even in the rain.it wont be perfect but at least you would have some shelter

but how did you pack up?

That would have avoided several fires at the university I used to work at...

Bromine is very rare in Australia because it breaks down in sunlight as I understand it. Do they only use it for indoor pools and spas in America? or is the UV just that much lower that it doesn't matter? I only know of one person who uses Bromine in their spa, and they have to drain the entire thing twice a year because it doesn't work :D

What is the name of the music.

If bromine is the kinetic product of yhis reaction, that will be because the reaction that produces bromine has a lower activation energy (than, I assume, the reaction that produces chlorine). Everything you say about the stirring is valid, so that would still need to be addressed; but if you carry out the reaction at a lower temperature, you should obtain a greater ratio of bromine to chlorine.

Why havent you made a hood fan for the shop yet? Just put a more powerful motor in a kitchen stove hood fan and make containment around/below it. Now you can make ammonia indoors if you do!

The world is your bin remember? you're just living by your motto!

You had made a video of bromine on 2014 for explosionsandfire

You have exactly the same pestle and mortar as me except mine is broken about halfway down where the black line is lol

Could you react the sodium bromide with sodium meta bisulfite and get the same results but even better without chlorine?

get one of those foldable outdoor sunshade things it would help with unexpected rain and cut down on uv radiation

i use potassium metabisulfite to clean my fermenting apparati' . its a disinfecting agent. and a flavouring agent. but could totally have use beyond that .

Are you working up to prepping NBS?

That was one of the uses I'd had lined up for it. I've bought some MSG, now I just wonder if I could make that whole thing NBS synthesis work, going via succinic acid, and is it going to be worthwhile? Or perhaps I just try another more brute force attempt at methallyl bromide by addition of bromine to liquid isobutene in pyridine

Surely you are going to hate me for it. But in the rain, the chemistry shots look fkn awesome!!! Start a new channel: Distilations & Rain ❤

they're awesome, they sell them in oz as well

also i guess like other parts in the world like here where i live, sodium/potassium metabisulphite is used in wine industry, since australia produce a lot of wine it should be easy to get huge amount right ?
