Zinc bromide
CAS No.7699-45-8
Alias: Zinc bromide (ZnBr2);Zinc bromide anhydrous;zincbromide(znbr2);zincdibromide;ZnBr2;ZINC BROMIDE;ZINC(II) BROMIDE;ZINC BROMIDE SOL. D20 2,5 OPTICAL GRADE FOR SHIELDED WINDOWS OF HOT CELLS
Molecular formula: Br2Zn
Relative molecular mass: 225.2
Structural formula:
1. Performance and use:
Zinc bromide is a white crystalline powder prepared by dissolving zinc carbonate in hydrobromic acid.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.
Optimal catalyst for stereospecific and regioselective reaction of silacyclopropanes with carbonyl compounds.
Making silver bromide collodion emulsions for photography; in the shielding of viewing windows for nuclear reactions.

3. Safety protection
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.
