What is Zinc Bromide Like?
Zinc bromide is a solid that has no color. It dissolves easily in water. When it dissolves, it creates a solution that is acidic. It is also hygroscopic, which means it can take in moisture from the air.
How is Zinc Bromide Made?
Scientists can make zinc bromide in a few ways.
- One way is to mix barium bromide with zinc sulfate. This reaction creates zinc bromide and also barium sulfate, which can be filtered out.
- Another method is to react zinc metal directly with bromine.
- It can also be made by reacting zinc with hydrogen bromide or hydrobromic acid.
What is Zinc Bromide Used For?
Zinc bromide has several important uses:
- It is used in a field of science called organic chemistry. This is the study of chemicals that contain carbon.
- It can act as a shield to protect against radiation. This is important in places where radiation might be present.
- There are special batteries that use zinc bromide to store energy.
