Hydrobromic Acid (HBr)
Pure hydrobromic acid is a clear, colorless, fuming corrosive liquid
with a strong, pungent odor. It is sensitive to light and heat, and
may take on an amber color during storage due to formation of free
bromine. The acid is commercially available in concentrations of 48%
and 62%.
Most piping systems suitable for hydrochloric acid can also be used
to handle hydrobromic acid. Unarmored plastic, glass and graphite
should be used with discretion since these materials are subject to
impact damage.
Hydrobromic acid is used in the preparation of various chemical
intermediates, synthetic dyes, drugs, perfumes, bromides and in
photography. |
