Description and Uses
Mercury(I) bromide or mercurous bromide, Hg2Br2, is a compound that changes color from white to yellow when heated and fluoresces a salmon color under UV light. It is used in acousto-optical devices. A very rare mineral is kuzminite, Hg2(Br,Cl)2. Mercury(I) bromide is formed through the oxidation of elemental mercury with elemental bromine or via the addition of sodium bromide to a solution of mercury(I) nitrate.
MERCUROUS BROMIDE is used as an analytical reagent, and also in the pharmaceutical industry.
