CONDENSING BROMINE

[spotlightman1234]

Holy crap that's scary!!! That's why you wear your respirator, and safety equipement children :)

[GemoVII]

Amazing video! There isn't the danger that the heat produced breaks the glass, even if it's pyrex? And.. please, can you tell me what are the products of the reaction? KBrO3 + H2SO4 ---> Br2 + ..? Thanks in advance

[Basco36]

@GemoVI the reaction is not that hot and won't break glass, I'm know where to buy these chemicals mine were given to me

[nickalisse1]

U remember the retort's volume?? Look like around 50ml to 100ml, someting like that?

[Basco36]

@nickalisse1 100ml it is

[DJFamou5]

Basco you are the only person, i know, who can do these experiments ;)

[abebenoob]

you can mix bromate and bromine and add a bit of acid. Be careful, last time i got the same odourful blow of bromine vapour and got sore throat next day.

[ubuntupokemoninc]

can i use hydrochloric acid?

[alessio3521]

NaBr + H2SO4 it work?

[alessio3521]

where can I find potassium bromate? can also work by mixing chlorine (gas) with sodium bromide?

[SuperHoneycutt]

YOU GUYS NEED TO BE CAREFUL . I USED TO WORK IN A BROMINE PLANT. THAT STUFF WILL BURN YOUR ASS UP.

[v1ssu]

u make Juice?? ;)

[Phacias]

0:32 It wasn't clever ;/

[TheCaptainLulz]

wow, thats a complicated setup. I use NaBr, HCl, and H2O2 as the oxidizer. It puts the elemental bromine in suspension. Than I simply heat it like youre doing. I find theres usually water vapour on top of the bromine but thats easy to draw off.

[glenwoofit]

What did you bubble the bromine gas through? was it water? I see there was a lot of waste alot of the bromine didn't condense mabe an acid dropper would work better so you could control the rate of the acid and slow the gas production down thus condensing more of the bromine?

[Radium1337]

good work

[chandlerbeckhoff]

so arent the biproducts B2 H2O and NAS2?

[Agentoxedo07]

Holy-Terrorist:>Bromine is very dangerous

for the cancer,

other, iodine chlorine fluorine is not causing cancer

[deckard154]

Could you tell me where you purchased your retort? Or was it created by a glassblower? It's a cutie :D

[albgk]

you can buy from any major chemical supplier (VWR, Alfa Aesar, etc...) but theirs will be expensive... i would look at united nuclear (they have one for $38)

[j822bosh]

I am in the process of making Iron(III)bromide to use as a purifying agent in removing chlorine from the bromine.

[j822bosh]

I have yet to try sodium chlorate on a bromide salt with acid. It might be easier and safer than using chlorine gas. Up to a 100% excess of chlorine can be used to ensure the bromine is replaced from solution. At 5 Celsius or less, a majority of the bromine deposits on the bottom of the reactor. It need a good washing with cold water becuase the bromine is trapped in sodium chloride crusts. It looks like crude petrol in rock layers :)

[mcclurem13]

I have Sodium Bromide, is there any way to extract the Bromine from it, in pure form, using electrolysis with a solution of it. I would like to extract the bromine from it with as least other chemicals as possible, to save money, but can you stop the bromine from dissolving in the solution in any way, or if not, can you later distill the bromine out of the water without letting too much water evaporate?

[pyropakman]

Make a supersaturated solution of it, and then bubble chlorine gas through it. Chlorine is much more electronegative than bromine, and thereby will abstract electrons from the bromide, creating a saltwater solution, along with elemental bromine.

[SplinterCell521]

does this only work with H2SO4?

[Basco36]

I think so

[vitorix24]

HCl

[196Stefan2]

@Basco36

It also works with concentrated H3P04 (85%) and an additional oxydising agent (KMnO4, K2Cr2O7), too, but use Potassiumbromide (or NaBr) instead the Bromate-Compound.

[Phacias]

@SplinterCell521 No, with every stronger acid than HBr.

[howe094]

nm, i did it for myself and it worked perfectly if you add some h2o2 to the mixture

and i suggest using denatured alcohol chillled in a freezer or with dried ice in order to cool the bromine vapor, since this prevents loss of bromine

[howe094]

by the way, do you chill your water in order to condense the bromine for a higher yield due to less gas escaping, or will it not make a difference?

[howe094]

hey, does anybody know what a solution of NaHSO4 combined with KBr will produce, because NaHSO4 is so much cheaper than H2SO4. And also, would the yield of bromine be equivalent?

[Chaoschemiker]

Bromate shouldn't yield more bromine than bromide. Anyway, bromate is more expensive.

The only advantage of bromate, is the self-oxidation of the bromide-ions, yielded by the reaction of bromate with sulfuric acis.

Damn! What lots of bromine vapors...

Hope you didn't inhalate too much of it.

What's your "other way" you mentioned (in a former comment "This is not my method for making bromine...") making bromine? I prefer using Chlorate as oxidizing agent for the bromide-ion (from KBr)

Greetings

[Basco36]

I make bromine by bubbling chlorine gas through a sodium bromide solution. I was planning to make a vid of it but never did.

[thedude77777]

this guy really likes halogens 0.o

[zasx20]

wats the powder in the rehotic

[Basco36]

Potassium bromate.

[Sebbass69]

When done with KI, hydrogen sulfide is releases - does this release H2S as well, and if done with KBr and not KBrO3, would that release H2S?

[derkozten]

With KBr, SO2 is the principal sulfur product (Although some H2S could be released)

2KBr + 2H2SO4 -> Br2 + SO2 + K2SO4 + 2H2O

I don't think it's the same situation with an oxidizing salt like KBrO3.

[stylcd]

next time to make it more efficient, pass the remeaining vapours through sodium hydroxide soloution (conc) to produce sodium bromide and sodium hypobromite. boil the remainding solotion and collect the crystals then dd conc H2SO4 and repeat the whole process more efficiently

:-)

[Bosnabosnan]

All that bromate and acid for that little bromine?!?!? A very inefficient method. Most of your bromine didn't condense but "flew away" as vapor.

[Basco36]

This is not my method for making bromine, It was just a demonstration using the retort. Thats why I name it condensing bromine. Yes this is very inefficient way of making bromine but the Bromine produced in this method comes out pure.

[youfuckingasshole69]

Why potassium bromate over potassium bromide? Wouldnt the bromate salt yield bromic acid?

[Basco36]

I believe both the bromide and bromate salt will yield hydrobromic acid. I chose the bromate salt cause it yields more bromine.

[derkozten]

I was wondering... if bromine is reduce from bromate (+5) to elemental form (0), what element is actually oxidized?

[Randumshitstudios]

what is H2SO2 exactly?

[Randumshitstudios]

Sorry H2SO4*

[Basco36]

oh, that is chemical formula for Sulfuric acid.

[derkozten]

ha, the first H2SO4 adding looked quite dangerous XD. And Br2 cooling, is in dry ice/acetone mixture?

Nice experiment; video quality can be improved, it's my suggestion.

[Basco36]

no, it was just is a salt ice bath.

[jmmatos23]

This shows how easily one can obtain a halogen! Great video! :D

[mabakken]

Very nice video! =)
