=Acidum Hydrobromicum Dilutum (Acid. Hydrobrom. Dil.), Diluted Hydrobromic Acid, U.S.P.=--HBr (about 10%).
A colorless, odorless liquid, with a strong acid taste. Incompatible with alkalies and their carbonates, metallic oxides and the salts of silver and of lead.
ACTION AND USES: In general, those of bromides; but the preparation is objectionable because of its acidity.
