Description
Mercurous bromide, also known as bromo mercury, is a chemical compound with the formula HgBr2. It is a white powder or colorless crystals that are odorless and tasteless. Upon heating, it turns yellow but returns to its original color upon cooling. It darkens when exposed to light. Mercurous bromide is soluble in fuming nitric acid (with prolonged heating), hot concentrated sulfuric acid, hot ammonium carbonate, or a mixture of ammonium chloride and ammonium hydroxide.

Check Digit Verification of cas no
The CAS Registry Mumber 10031-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10031-18:
(7*1)+(6*0)+(5*0)+(4*3)+(3*1)+(2*1)+(1*8)=32
32 % 10 = 2
So 10031-18-2 is a valid CAS Registry Number.

A Flowing-Afterglow Study of the Quenching Reactions of Hg(3P2) and Hg(3P0) Atoms by Halogens, Interhalogens, and Polyatomic Halide Molecules
Zhang, Fu Min,Oba, D.,Setser, D. W.
, p. 1099 - 1114 (1987)
Mercury (3P2) and (3P0) metastable atoms were prepared in a flowing afterglow reactor by passing He, Ne, or Ar carrier gas containing Hg through a dc discharge.The interaction of Hg(3P2) with 30 halogen-containing molecules (325 K) was studied by observation of the HgCl, HgBr, and HgI(B2Σ+-X2Σ+) chemiluminescent spectra.Intramultiplet relaxation to Hg(3P1) also was monitored for some of these molecules plus NH3, CH4, and CF4 and five nonreactive diatomic molecules.The addition of N2 to the flow reactor removes the Hg(3P2) atoms and the reactions of Hg(3P0) can be isolated.The branching fraction for HgX(B) formation, X = Cl, Br, and I, is much lower for Hg(3P0) than for Hg(3P2) reactions.Computer simulation of the HgX(B-X) spectra provided nascent HgX(B) vibrational distributions.The reactions of Hg(3P2) with halogens, mixed halogens, and ICN resemble the analogous Xe(3P2) atom reactions with regard to product branching fractions and energy disposal.These data are discussed in terms of the covalent-ionic curve-crossing reactive quenching mechanism.Upper limits are set for the bond energies of CF3NCl-Cl, CF3NCl-Br, CF2ClNCl-Cl, CF2ClNF-Cl, CF2N-Cl, and CF2BrCF2-I from the HgX(B-X) spectra.The B- and X-state potentials of HgCl, HgBr, and HgI were improved relative to our prior work to better simulate the HgX(B-X) spectra.The excitation-transfer reaction between Hg(3P0,2) and CN was observed as a secondary reaction with BrCN and ICN.
