Why bromine should be kept cold and in a fume cupboard?
Bromine is a highly reactive and toxic liquid with a low boiling point, so it can easily vaporize at room temperature. Storing it in a fume cupboard prevents exposure to its toxic fumes, and keeping it cold helps to minimize its volatility and decrease the risk of accidental spills or releases.
