The correct chemical formula for cadmium bromide is CdBr2.
Cadmium bromide is an inorganic compound known for its specific chemical composition. It is typically found as a white, hygroscopic solid, meaning it readily absorbs moisture from the air.
Understanding Cadmium Bromide
This compound is a salt formed between cadmium (Cd), a transition metal, and bromine (Br), a halogen. The formula CdBr2 indicates that one cadmium atom is chemically bonded with two bromine atoms.
Here's a quick overview of its key characteristics:
| Property | Description |
|---|---|
| Chemical Formula | CdBr2 |
| Appearance | White solid |
| Hygroscopy | Hygroscopic (absorbs moisture from the air) |
| Classification | Inorganic compound |
Different Forms of Cadmium Bromide
Beyond its anhydrous form (CdBr2), cadmium bromide can also exist in hydrated forms, where water molecules are incorporated into its crystal structure. These common forms include:
- Anhydrous Cadmium Bromide (CdBr2): The pure form without water molecules.
- Cadmium Bromide Monohydrate: Contains one molecule of water per formula unit.
- Cadmium Bromide Tetrahydrate: Contains four molecules of water per formula unit.
These hydrated forms are also white solids and are obtained depending on the synthesis conditions and presence of moisture. For more detailed information on its properties and uses, you can refer to resources like Cadmium bromide.
