Chemical Properties
Zinc bromide is a typical ionic compound, which can undergo various ionic reactions in aqueous solutions. It can react with some metal salts to form insoluble bromides or complex compounds. For example, it can react with silver nitrate to form silver bromide precipitate. It can also react with strong bases to form zinc hydroxide precipitate.
Uses
Medicine: It has certain antiseptic and astringent effects and is used in some pharmaceutical preparations.
Chemical Industry: It is used as a catalyst in some organic synthesis reactions, such as in the alkylation and acylation reactions of aromatic compounds. It is also used in the production of other zinc - containing compounds.
Photography: It is used in the production of photographic emulsions, playing a role in improving the sensitivity and contrast of photosensitive materials.
Electrolytes: It can be used as an electrolyte in some batteries and electrochemical systems due to its good solubility and ionic conductivity.
Safety Information
Zinc bromide is irritating to the eyes, skin, and respiratory tract. Direct contact with the skin or eyes may cause irritation and burns. In case of inhalation or ingestion, it may cause harm to the body, including irritation of the respiratory system and digestive system.
It should be stored in a dry and ventilated place, away from moisture and strong oxidants. When handling, appropriate protective measures should be taken, such as wearing gloves and goggles.
