Barium Chloride Formula, which is also known as Barium Dichloride. Barium Chloride is a soluble salt of barium formed by the direct reaction between chlorine and barium.

A white solid, it is hygroscopic and soluble in water. It crystallizes into two polymorphs: cubic fluorite (CaF2) and orthorhombic cotunnite (PbCl2).

Toxic and inexpensive, it can be used to test sulfate ions, purify brine solutions, and make pigments and other barium salts.

Barium Chloride Formula 

The chemical formula for barium chloride is BaCl2. It is composed of the metal cation barium (Ba²⁺) and the anion chloride (Cl⁻). Barium chloride is a white, crystalline solid with high solubility in water.

Barium Chloride + Aluminum Sulphate

When barium chloride (BaCl2) reacts with aluminum sulfate (Al2(SO4)3), it leads to the formation of barium sulfate (BaSO4) and aluminum chloride (AlCl3). This reaction is a classic example of a double displacement reaction, where ions from two different compounds swap partners, producing two new compounds.

Barium Chloride Formula – Molar Mass and Molecular Weight

The molar mass of the barium chloride formula (BaCl2) can be calculated by adding the atomic masses of its constituents. Barium (Ba) has an atomic mass of approximately 137.33 g/mol, and chlorine (Cl) has an atomic mass of around 35.45 g/mol. So, the molar mass of barium chloride is approximately 137.33 g/mol (Ba) + 2 * 35.45 g/mol (2 Cl) = 208.23 g/mol. The molecular weight is the same as the molar mass.

Barium Chloride + Sodium Sulphate

When barium chloride formula reacts with sodium sulfate (Na2SO4), it produces barium sulfate (BaSO4) and sodium chloride (NaCl). This reaction is another example of a double displacement reaction and is used in chemistry for the precipitation of barium sulfate.

Barium Chloride Formula – Uses

Barium chloride has several applications. One of its primary uses is in the production of barium sulfate, which is used in diagnostic radiology as a contrast agent. It is also employed in the manufacturing of pigments, dyes, and ceramics. Additionally, barium chloride is used in the purification of brine solutions and in the chemical industry.

Barium Chloride Solution

Barium chloride can be dissolved in water to form a barium chloride solution. This solution is commonly used in laboratory experiments and industrial processes. It is important to handle barium chloride with care, as it is toxic and should not be ingested.

Barium Chloride Reacts with Zinc Sulphate

When barium chloride reacts with zinc sulfate (ZnSO4), it results in the formation of zinc chloride (ZnCl2) and barium sulfate (BaSO4). This reaction is yet another example of a double displacement reaction and can be used for the qualitative analysis of sulfate ions, as barium sulfate is highly insoluble and forms a white precipitate.

Barium Chloride Configuration

In barium chloride formula, one barium atom gives up two of its outermost electrons to two chlorine atoms to form an ionic salt. An ion is electrostatically attracted to two Cl−.  The ions that form the ionic salt barium chloride. The shape of BaCl2 it bends.

Based on the placement of the constituent ions within the structure, barium chloride exhibits polymorphism and can take on two crystalline forms.

Structure of cubic fluorite

In the fluorite structure, barium is 8-coordinated, and chloride is 4-coordinated. Chloride ions occupy all tetrahedral sites in a cube, forming a cubic close-packing arrangement.
