Bromine

[elaruu]

Hi all. A teacher has asked for pure Bromine, as opposed to Bromine water. This is teacher only, however he said he would demonstrate. Does anyone know where I would be able to source this? I can't seem to find anyone selling it.

Thanks!

You can get Bromine from Merck (very expensive for a once off demo), we only have the Bromine water on site... I have said 'no' to requests for anything different.

Hmmm. He says it is an essential part of the curriculum.....

I would run it past head of science

I'd be reluctant to have bromine around - bromine water is horrible enough.

Me too

For those who refuse to make up bromine water from scratch. (had a bad accident).
Georgia Deretic who co-wrote Foschem Senior Chemistry gave me a substitute that works just as well and less dangerous.

Bromine in Situ
100 mls 2m Sulfuric Acid
50 gms Potassium Bromide
Dissolve
Add drop by drop of Hydrogen Peroxide (100 vol) till deep brown colour.
