Uses
Zinc bromide is a white crystalline powder prepared by dissolving zinc carbonate in hydrobromic acid. Zinc chloride (ZnCl2? is a white granular crystal made by the action of hydrochloric acid on zinc. Zinc iodide (ZnI2) is a white powder made by dissolving zinc in ionic acid. All of the zinc halides are soluble in water, alcohol, and ether. They were all used as halides for the collodion emulsion processes.

Hazard Information

General Description
A white crystalline noncombustible solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. ZINC BROMIDE(7699-45-8) is used in medicine, in photography.
Reactivity Profile
Acidic inorganic salts, such as ZINC BROMIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Air & Water Reactions
Hygroscopic. Water soluble
Health Hazard
Inhalation of dust may irritate nose and throat. Ingestion can cause irritation or corrosion of the alimentary tract; if large amount is swallowed and not thrown up, drowsiness and other symptoms of bromide poisoning may occur. Contact with eyes or skin causes irritation.
Potential Exposure
Zinc bromide is used in photography, rayon manufacturing and medicine
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Shipping
UN3260 Corrosive solid, acidic, inorganic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Incompatibilities
Keep away from alkali metals. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, metallic sodium, or potassium. Store above 32 ℉/0℃.

Questions And Answer

Description
Zinc bromide (chemical formula: ZnBr2) is an inorganic compound consisting of zinc and bromide. It is manufactured through the reaction between zinc oxide (alternatively, zinc metal) with hydrobromic acid, alternatively by the reaction between zinc metal and bromine. It is a kind of Lewis acid in organic chemistry. It can be used as the electrolyte in the zinc bromide battery. In oil and natural gas industry, its related solution can be used to displace drilling mud. Moreover, its solution can be used as a transparent shield against radiation. Finally, it can be used as a catalyst for the Stereospecific and regioselective reaction between silacyclopropanes with carbonyl compounds.
