Hi
I have this recepy that we follow:
Bromine water from Chlorine-based household bleach and Sodium Bromide
to make 50 ml bromine water, you will need:
glass bottle with screw cap
1.1g sodium bromide,NaBr
10.7ml 1 M HCl
7.6 ml sodium hypochlorite (household laundry bleach)
32 ml water ( distilled)

Dissolve the NaBr in the HCl and transfer to the labeled bottle. Add the sodium hypochlorite to the bottle and swirl to mix the reagents .
Keep the bottle capped when not in use .

Good luck
Celia

Hey Pam
When I make mine, I keep it in the Fridge, it has very short shelf life.
It comes off as gas out of solution and should have reddish tinge to yellow
