Remarks
Deep red, dense, sharp smelling liquid, Br2. Compounds used
in fuel additives, pesticides, flame-retardants, and photography. Bromine
is recovered from sea water and oil field brines.
Diagnostic tests:
Bromine salts (along with F, Cl, and I) will give a blue color to flames
when heated on a copper disk.
Treatment of the salt with concentrated H2SO4 acid will effervesce with
the evolution of a brown gas (Br2). Bromine is always found associated
with chlorine or iodine so a precipitate with AgNO3 solution is white (AgCl),
cream (AgBr), or yellow (AgI) depending on which anion predominates.
