Barium Bromide Formula

Chemical Formula:

It is an inorganic compound in the form of barium and bromine. Barium bromide can be found in the form of dihydrate (BaBr₂·2H₂O).

Physical Properties:

Appearance

For the most part, barium bromide is always found to be in white crystalline powder form. Being a crystalline solid, it has a very distinctive structure, thus applicable in applications where purity and consistency play the most important factors.

Molecular Weight:

The molecular weight of barium bromide is 297.13 g/mol, which is a sum of the weight of barium (Ba) atoms and bromine (Br) atoms in a molecule.

Melting Point:

The melting point of barium bromide stands at approximately 798 °C or 1,468 °F. This high melting point is interpreted to mean that it is a thermostable compound and thus readily resists decomposition by high temperature applications.

Solubility:

The salt is soluble in water; it has a solubility of about 57 g per 100 mL at 20 °C. Its characteristic can be used in a lot of different aqueous solutions, such as chemical reactions and laboratory procedures. It is slightly soluble in alcohol.

Density:

The density of barium bromide is about 4.86 g/cm³, which is very high in comparison to the density of water. This makes one of the factors for its behavior in different mixes and solutions.

Hygroscopicity:

Barium bromide is hygroscopic and thus develops the ability to absorb moisture in the air. So its storage has to be done cautiously for protection from stability loss or agglomeration or degradation.

Chemical Properties

Ionic Nature:

Barium bromide is an ionic compound containing barium ions (Ba²⁺) and bromide ions (Br⁻). This makes the compound ionic in nature, resulting in a high melting point and high solubility in water.

Solubility in Water:

Barium bromide can dissolve very significantly in water and breaks into barium ions and bromide ions

 

This is why it forms part of many aqueous chemical reactions and processes

Reactivity with Acids:

Barium bromide is known to react with concentrated acids to give bromine and barium salts. For example, it reacts with sulfuric acid to give barium sulfate and hydrobromic acid

Preparation of Barium Hydroxide:

On reacting barium bromide with strong bases such as sodium hydroxide, one can get barium hydroxide and a bromide salt.

Thermal Stability:

Barium bromide is thermally stable within its melting point, although it may decompose when heated to a higher temperature than that, especially if moist or stored in the presence of other reactive agents.

Precipitation Reactions:

Precipitation reactions involving barium bromide occur commonly with sulfate ions. BaSO₄ is also insoluble

Complex Formation:

The barium ion complexes with virtually any ligand in aqueous solution. This can greatly affect the reactivity of a compound as well as practical uses in analytical chemistry.

Application
