Barium chloride Specification

Barium chloride is the ionic chemical compound with the formula BaCl2. The substance has the CAS register number 10361-37-2 and EINECS number 233-788-1. It is stable, but incompatible with other materials like bromine trifluoride and furan-2-peroxycarboxylic acid. Barium chloride anhydrous is a white solid. Any of a variety of substances that contain barium. Most are whitish colored crystalline solids. They tend to be soluble in water and denser than water. They may be toxic by inhalation or possibly skin absorption.Barium chloride anhydrous is non-combustible. The substance itself does not burn but may decompose upon heating to produce corrosive and toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. In additionm, when heated, its container may explode.

Properties of Barium chloride:
Barium chloride anhydrous may react violently with BrF3 and 2-furan percarboxylic acid in its anhydrous form. Barium chloride can react with sulfate ion to generate a thick white precipitate of barium sulfate. Moreover, it can react with oxalate to give barium oxalate. The reaction equations are as the follwing:
Ba2+(aq) + SO42-(aq) → BaSO4(s)
Ba2+(aq) + C2O42-(aq) → BaC2O4(s)

Preparation of Barium chloride:
Barium chloride anhydrous is produced by barium hydroxide or barium carbonate. And then Barium chloride anhydrous reactS with hydrochloric acid to give hydrated barium chloride. In industry, it is prepared via a two step process from barium sulfate at high temperature. Afterward, The second step requires fusion of the reactants. The Barium chloride can then be leached out from the mixture with water.
BaSO4 + 4 C → BaS + 4 CO
BaS + CaCl2 → BaCl2 + CaS
In addition, Barium chloride can also be prepared by heating Barium chloride dihydrate at 125 °C. The reaction equation is as following:
BaCl2.2 H2O → BaCl2 +2 H2O

Uses of Barium Barium chloride:
 Because it is a cheap and soluble salt of barium, Barium chloride anhydrous is widely used in the laboratory. In industry, Barium chloride anhydrous is mainly used in the purification of brine solution in caustic chlorine plants and also in the manufacture of heat treatment salts, case hardening of steel, in the manufacture of pigments and other barium salts. It is commonly used as a test for sulfate ion. Barium chloride anhydrous is also used in fireworks to give a bright green color.

Safety information of Barium chloride:
When you are using Barium chloride anhydrous, you should be very cautious about it. It is toxic if swallowed and harmful by inhalation. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible).

Descriptors computed from structure of Barium chloride anhydrous:
(1)Canonical SMILES: [Cl-].[Cl-].[Ba+2]
(2)InChI: InChI=1S/Ba.2ClH/h;2*1H/q+2;;/p-2
(3)InChIKey: WDIHJSXYQDMJHN-UHFFFAOYSA-L
