Properties
Chemical
Bromine water is often used as a reactive in chemical assays of recognition for substances which react with bromine in an aqueous environment with the halogenation mechanism, such as alkenes, phenols, enols, acetyl groups, aniline and glucose.
Physical
Bromine water is a yellow solution, with a strong, unpleasant and hazardous smell.
Production
Bromine water can be produced by carefully dissolving elemental bromine in water. It can also be produced by mixing a bromide salt with an oxidizer and an acid, such as sodium bromide with bleach and hydrochloric acid.
Projects
- Alkene detection
Handling
Safety
Bromine water is corrosive to metals and tissues, especially in case of skin, eye, nose.
Storage
Bromine water will convert to hydrobromic acid, and should be stored in closed glass bottles, with a corrosion resistant lid.
Disposal
Bromine water can be neutralized with sodium bisulfite or sodium thiosulfate solutions.
