Making bromine

- In this video we are making bromine by reacting sodium bromide with chlorine gas. The chlorine gas was produced from TCCA and hydrochloric acid.

Wow, that was really clear explanation. Appreciate the attention to safety, as well. I make my own solutions for developing photographic film and other things like modified cyanotypes. Between supply-chain shortages and strict US laws regarding sales and imports to private citizens, I've ended up directly synthesizing more and more of the components, myself. I think I enjoy the chemistry now as much as the photography haha. Not sure I will ever mess with Bromine, but it's cool to see!
You wouldn't happen to know anything about the photochemistry of colorful photography would you? I mean like how electrons are transferred from the silver to the photosensitizers and dyes? Maybe a good reading reference?
If not, it does sound like you might know something about urano typing I'd love to try that!
Stir fish 🤣 That's awesome!
Stir bar sounds boring. Let’s give this word the love this useful invention deserves!
@@THYZOID You know my opinion on magnetic stirring, one of the most important equipment inventions of the past hundred years in chemistry!
Nice results! Although that sounds like a lot of HCL, so I've calculated it to double check before I do this myself, and I got 95ml HCL at 33% instead of the 190ml. I guess I'll test this and see if it works or not lol
Absolutely perfect. Bravo!)
I tried this extraction for bromine from sodium bromide in an gas stove instead for hot plate and all of a sudden i heard an bang the fun fact was it happened all of a sudden i was not even wearing an gas mask.I barely made out of the house and i was coughing like hell for 2days i honestly thought that this is the end of my journey with chemistry 😂 thank god i survived
Have u considered using the bromine to dissolve or purify gold?
Haven’t thought about it yet but I thought about using chlorine. Gold is sadly one of those chemicals you don’t have standing around in the corner.
Yeah you definitely need those Teflon lined lids, that ain't something I should be keeping in an old spaghetti jar with metal lid. ..
Woaw 👀
Good job 👋👍
Very cool. Aluminum and bromine is my absolute favorite reaction but it's such a hassle to make the bromine and even more to do the reaction!
I have some sodium bromide, half of it is reserved for bromine and the other half is for bromate. I'll definitely be doing it outside!
Well, great! And now use another drying agent instead of sulf acid, that would be just nice! In Germany we‘ve got the problem sulf acid will not be selled anymore in a few months.
@@THYZOID I don't get it...
@@THYZOID One can still use his fists to injure someone bad enough to put him in the hospital. So are they gonna have to restrict or even ban the use of our hands in public in the future?
@@redmadness265 es geht eher um Sprengstoff herstellung.z.bTNT (= TriNITROtoluene) wofür man Schwefel- und Salpetersäure braucht - deshalb das verbot
I need your help, I tried this but the nike red way by putting it all in the same chamber, I also used potassium bromide.
So KaBr, HCl ane TCCA in one flask, didnt take long for brown vapours to form.
I used liquid propane as a coolant in hops of getting solid bromine and reducing vapors, but it just didnt freeze, I even tired with dry ice and it was still liquid.
What did I create? HBR?
(I put it in warm water to boil any liquid chlorine off )
I cant think of anything that makes sense, HBR should have boiled off, bromine should have been frozen solid and Hydrobromic acid should have been frozen too.
Bilden sich keine Interhalogen Verbindungen die das Brom kontaminieren? ClBr zb?
Doch und daher werden wir in Zukunft auch noch einen weiteren Reinigungsschritt unternehmen
@@THYZOID Klingt gut, wie sähe dieser aus?
BrCl + NaBr ---> Br2 + NaCl
Im Endeffekt wird unreines Brom und eine große Menge NaBr unter Rückfluss 1h lang erhitzt.
@@THYZOID Gibt es über die Bildung von Interhalogenverbindungen irgendwo Literatur? Das dies ein Problem sein soll, ist mir neu. Schließlich erfolgt die großindustrielle Bromherstellung nach dem gleichen Prinzip mit Chlor als Oxydationsmittel, das im Gegenstrom durch bromidhaltige Salzlösungen geblasen wird. In der Sendung im "Studienprogramm Chemie" über die Halogene wird so eine Pilotanlage kurz gezeigt.
For long term storage ampule is best and how I store my element sample for my elements periodic table.
it depends on how often you need bromine and how much you have. with the big amounts i tend to make ampoules are a bad choice. glass bottles with a ptfe lined lid and the bottle in the fridge are ideal
was für eine temperatur benötigt man für die destillation?
ach ja kann man auch pooltableten anstatt von TCCA und salzsäure benutzen?
ok this is all great but can not get Sodium Bromide is there any other way >
Very nice!but can you use O3 generator for Br2?to oxidate NaBr to bromine.....how coud be the yeld impact?
It would be possible but generating large amounts of O3 in a short time period would be extremely hard.
Haha hab ich wohl doch richtig gesehen dass du auf reddit warst 😂
nice!.
coool
Where do you get the duran ptfe lids, they seem hard to find and i've cut ptfe seals from sheet in the past.
Got them at a shop nearby. Indeed they are hard to find especially online.
What is full form of TCCA???
trichloroisocyanuric acid
Wow that’s a nice yield
Seems a bit too high to me with all the loses we saw during the process. I suspect a small calculation error somewhere.
Nicht schlecht, aber das hat NileRed auch schon lange gemacht. Wieso nicht in Deutsch? Das wäre was neues auf RUclips!
Auf englisch kann ich mehr Interessierte erreichen. Nilered hat glaube ich das Cl2 nicht eingeleitet sondern direkt alles im Destillationskolben gemischt.
