| Hazard Information | Back Directory | [Chemical Properties]
Mercuric Bromide is a crystalline solid | [Chemical Properties]
white crystalline powder | [General Description]
White rhombic crystals. Sensitive to light. Slightly soluble in water and denser than water. Severely toxic by inhalation and ingestion. | [Reactivity Profile]
MERCURIC BROMIDE(7789-47-1) is incompatible with acetylene, ammonia, chlorine dioxide, azides, calcium (amalgam formation), sodium carbide, lithium, rubidium, copper . 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. | [Air & Water Reactions]
Slightly soluble in water. | [Hazard]
Toxic by inhalation, ingestion, and skin
absorption; strong irritant. | [Health Hazard]
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | [Potential Exposure]
This compound has applications in
medicine. | [Fire Hazard]
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion,
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed. As
first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. Antidotes and Special Procedures for medical
personnel: The drug NAP has been used to treat mercury
poisoning, with mixed success. | [Shipping]
UN1634 Mercuric bromides, Hazard Class: 6.1;
Labels: 6.1-Poisonous materials | [Incompatibilities]
Violent reaction with active metals;
potassium, sodium. Store away from heat and light | [Description]
Mercuric Bromide is a crystalline solid. Molecular weight= 360.41;Boiling point=322℃; Freezing/Melting point=236℃. Hazard Identification (based on NFPA-704 M Rating System): Health 3, Flammability 0, Reactivity 0. Slightly soluble in water. | [Definition]
ChEBI: Mercury dibromide is a mercury coordination entity composed of mercury and bromine with the formula HgBr2. | [Purification Methods]
Crystallise it from hot saturated ethanolic solution, dry and keep it at 100o for several hours under a vacuum, then sublime it. [Garrett J Am Chem Soc 61 2744 1939.] Its solubility in H2O is 0.6% at 20o, and 22% at 100o; in EtOH it is 30% at 25o; and in MeOH it is 69.6% at 25o. [Wagenknecht & Juza Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1109 1965.] POISONOUS. | [storage]
Color Code—Blue: Health Hazard/Poison: Store in a secure poison location. Prior to working with this chemical you should be trained on its proper handling and 1684 Mercuric bromide storage. Store in tightly closed containers in a cool, wellventilated area away from light, heat, and acids. Mercuric bromide must be stored to avoid contact with sodium and potassium, since violent reactions occur. |
