This experiment should be done in a fume cupboard
The bromine water test is on our IGCSE Chemistry specification as a required practical. And yet the procurement of bromine water can be problematic.
A quick substitute for bromine water on a small scale can be improvised using household bleach, 2M hydrochloric acid and potassium bromide solution.
Lot's of interesting chemistry to discuss and the bromine generated is decolourised by the addition of an alkene quite nicely.
I am sure this has been done many times before.
