Hiya
What is the best way to store bromine water? In our chem store room I have 1 corrosives cupboard and 1 oxidising cupboard, then just the shelves. I have been storing it with the corrosives - but would it be safer with the oxidisers? I know it is not compatible with either so it is just a matter of which is the safest,

Thanks
Kathryn

Keep it in the fridge

Hi Kathryn,

We store ours in the fridge, after advice from previous threads on this forum, but I just checked CSIS to clarify what it says.

Have a look yourself - it does say store in refrigerator.

If you are making it up fresh, it doesn't last long. We buy it in 500mL bottles, and are still using a bottle bought before I came here 3 yrs ago, with good results. (I am very happy to not to have to make it up from bleaching powder and potassium bromide as at the last school).

However, the general rule is to store as the first class mentioned, so using this as an example, as DG8.

I keep ours in the fridge. Last year after reading someone's post (probably lizzieb's) I bought the ready made Bromine Water after looking at how to make it using bromine liquid. There was no way I was going down that path. The HT (also the chemistry teacher) was really happy with it, better than what had been served up previously.
I used the same bottle 12 months later and it was still good. I guess it will still be going in another 12 months.
