Zinc bromide white diamond crystalline powder. The density of 4.201 g/cm3. Melting point is 394 ℃. The boiling point of 650 ℃. Soluble in water, alcohol, acetone, tetrahydrofuran. Dissolved in ammonia. It's insoluble in ether. It is made by distillation of pure zinc and bromine. Used as finishing agent for rayon. It can also be used in medicine and photography.
Zinc bromide avoids contact with water, oxides. Soluble in water, alcohol, ether and acetone, alkali metal hydroxide solution. When the temperature is higher than 37 ℃, solid phase with aqueous solution into balance is no water. Soluble in water, soluble in ethanol, ether, acetone and ammonia. When heated in hydrogen, zinc bromide is reduced to zinc, and it reacts violently with hot alkali metals. When red is hot, oxygen turns it into bromo oxide, and fluorine turns it into zinc fluoride.
