Molecular Formula | Br- |
Molar Mass | 79.904 |
Nature:
1. Usually in solid or solution form, with a white or light yellow appearance.
2. It has chemical properties similar to chloride ions and usually has a negative charge.
3. Has a certain solubility and can dissolve in water to form bromide ions.
4. Bromides can form compounds with other metals under certain conditions, such as silver bromide.
Usage:
Bromides are widely used in industrial fields such as organic synthesis and dye preparation.
Method:
Bromides can be prepared by dissolving bromine or hydrobromic acid in water and reacting with alkaline bromide. For example, sodium bromide can be obtained by reacting hydrobromic acid with sodium hydroxide, and then pure bromide can be obtained by alcohol acid method or cation exchange method.
Security information:
1. Bromides can irritate the eyes, skin, and respiratory tract, and may have a certain impact on human health.
2. When using bromide, attention should be paid to avoiding contact with skin and eyes, and maintaining a well ventilated environment.
3. When storing and handling bromide, attention should be paid to its corrosion and irritancy to avoid mixing with other chemicals.
4. If accidental contact or inhalation of bromide occurs, immediate emergency treatment and medical attention should be sought.
