Properties
and storage:
Hydrobromic acid is a concentrated solution of
hydrogen bromide gas in water. Solution with strengths
higher than about 48 per cent fume freely when
exposed to the atmosphere.
These
fumes are extremely corrosive and an irritant
to the mucous membrane. A solution of less than
48 per cent is usually easier to handle and store.
Hydrobromic acid is sensitive to light, which
slowly decomposes it and imparts to it a reddish-brown
colour.
Uses: Concentrated hydrobromic acid is
used principally in the preparation of certain
organic chemicals and vitamin A.
Packing:
40- to 55-kg HDPE container.
