Is Mercury bromide soluble in water?
Mercury (I) bromide (mercurous bromide) is a white-yellow powder that darkens on exposure to the light and is quite insoluble in water. Mercury (II) bromide (mercuric bromide) is a white crystalline powder that is also sensitive to light, and is somewhat soluble in water (6.1 mg / mL at 25°C (Handbook of Chemistry and Physics)).
What is the name of the compound formed when Mercury reacts with bromine?
Mercury forms two compounds with bromine: mercury (I) bromide and mercury (II) bromide. Mercury (I) bromide (mercurous bromide) is a white-yellow powder that darkens on exposure to the light and is quite insoluble in water.
How do you make Mercury bromide from mercuric salt?
Mercury(II) bromide can be manufactured by: adding potassium bromide to a solution of mercuric salt and crystallizing; by precipitation using a mercury(II) nitrate and sodium bromide solution; by dissolving mercury(II) oxide in hydrobromic acid.
What is the use of mercury (II) bromide in the laboratory?
Mercury (II) bromide is used as a reagent in the Koenigs–Knorr reaction, which forms glycoside linkages on carbohydrates. It is also used to test for the presence of arsenic, as recommended by the Pharmacopoeia. The arsenic in the sample is first converted to arsine gas by treatment with hydrogen. Arsine reacts with mercury (II) bromide:

What is the effect of potassium and mercuric bromide on impact?
A mixture of potassium & /mercuric bromide/ produces a strong exposion on impact.
What is mercury in the atmosphere?
Some other mercury compounds which may exist in the atmosphere are mercuric chloride, mercuric bromide, mercuric hydroxide, mercuric sulfide, and mercuric cyanide (1). The rest is elemental mercury in the gaseous phase. In remote areas over the Atlantic and Pacific oceans, mercury bound to particulate matter concns are generally at or below the picogram per cubic meter level (1).
Is mercuric bromide soluble in water?
Mercuric bromide appears as white rhombic crystals. Sensitive to light. Slightly soluble in water and denser than water. Severely toxic by inhalation and ingestion. CAMEO Chemicals. Mercury dibromide is a mercury coordination entity composed of mercury and bromine with the formula HgBr2.
Is mercury a hazardous waste?
D009; Mercury. A waste containing mercury may or may not be characterized as a hazardous waste following testing by the Toxic ity Characteristic Leaching Procedure as prescribed by the Resource Conservation and Recovery Act (RCRA) regulations. / Mercury /
Is mercuric bromide a HAP?
Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Mercuric bromide is included on this list.
What is SCBA in fire?
Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible. (ERG, 2016)
Is mercury bromide an oxidizing agent?
MERCURY BROMIDES are easily reduced to give elemental mercury and thus serve as mild oxidizing agents. React with sodium azide to give products that are sensitive to shock, friction, and heat. A combination of mercury (II) bromide and hydrazine salts in base produced a heat- or shock-sensitive yellow precipitate [Annalen, 1899, 305, 191]. Combine violently, often with ignition, with chlorine trifluoride.
About Mercury Bromide
Mercury Bromide is a highly water soluble crystalline Mercury source for uses compatible with Bromides and lower (acidic) pH. Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications.
Packaging Specifications
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum.
Recent Research
Improved sensitivity and reproducibility in electrochemical detection of trace mercury (II) by bromide ion & electrochemical oxidation.
What is the reaction of sodium azide to mercury?
Reacts with sodium azide to give mercury (II) azide, which is sensitive to shock, friction, and heat. Mixing with hydrazine salts in basic solution produced a heat or shock sensitive yellow precipitate [Annalen, 1899, 305, 191]. Reacts violently with chlorine trifluoride *with ignition often occurring.
