Properties
and storage:
Liquid
bromine is a dark, reddish-brown, fuming, volatile
liquid with a suffocating odour. Bromine attacks
all metals and organic tissues. It vaporises at
room temperature.
One
litre of bromine weighs about 3.1 kg. One ml of
bromine dissolves in about 30 ml of water. It
is freely soluble in alcohol, chloroform, ether,
carbon disulphide, carbon tetrachloride and concentrated
hydrochloric acid. Liquid bromine should be stored
in well-stoppered containers.
Normally,
bromine is stored in amber-coloured glass containers
or glass-lined steel tanks, but dry bromine can
be stored in well-designed lead-lined or monel
drums.
Uses: Bromine is used primarily in the
manufacture of organic and inorganic bromides.
It is an important reagent in the preparation
of organic compounds involving a bromination step.
It is also used in water treatment, shrink-proofing
wool, as an intermediate for fumigants, as fire-extinguisher
fluid and military poison gas.
Safety
precautions: While handling bromine, always
keep ammonia water within reach.
Packing: 3- and 3.5-kg glass bottles.
