Producing bromine by reacting sodium bromide with sulfuric acid

Concentrated sulfuric acid is added to a beaker containing white crystals of sodium bromide. The essential product is bromine, some of which turns to the vapor phase immediately.

What would happen if u had put an aluminium foil in it?? Would it had reacted just as if it was just bromine??

@nickalisse1

I'm sure you would see the violent reaction between the two, perhaps not as strong since there are a lot of impurities still present here. I'm confident enough to say there would be some form of very exothermic reaction.

@mrteverett Tnks to have answered so soon. What about using a 35% liquid sodium bromide, instead of the diluted crystals?? Something different?? Any unwanted compound in it??

@nickalisse1

I don't know that a solution would have worked better. When I referred to unwanted compounds, I was referring to the fact that I did not stoichiometrically determine the mass of each reactant before I started. I just mixed a little of this and that and let it go. So, while the leftover reactants wouldn't necessarily interfere with the reaction, it might impact the visual effect.

@mrteverett Boil the bromine to it's boiling point (58.8 C, can be done by any heat source) while trapped in a flask (ground glass joint), or a really big flask can just be used. Then 'pour' the bromine gas (it being much heavier than air) into a beaker in an ice bath to let it recondense. This should purify the bromine.

it's brominated orange pop!

you'd also get some sulphur dioxide, water, hydrogen bromide and sodium hydrogen sulphate.

Pretty damn nice.
