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!

Re: Bromine
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.

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