Crude bromine water

Bromine water is a highly oxidizing intense yellow mixture containing diatomic bromine Br2 at 2.8% dissolved in water.

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, hazardous smell.

Production

Bromine water can be produced by dissolving elemental bromine in water.

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.
