Barium chloride (BaCl2) is a salt of barium and chlorine. It is ionic and water-soluble. It is toxic like other barium salts. It imparts a yellow-green coloration to a flame.

Contents

Chemical properties

Since barium chloride is soluble in water, it can react with sulfate ion to produce a thick white precipitate of barium sulfate.

BaCl2(aq) + SO42-(aq) → BaSO4(s) + 2 Cl-(aq)

Barium chloride behaves as a simple salt, and it is completely neutral in solution.

Preparation

Barium chloride may be prepared from barium hydroxide or barium carbonate (found naturally as witherite) reacting with hydrochloric acid. On an industrial scale, it can be prepared via a two step process from barite (barium sulfate)[4]:

BaSO4 + 4 C → BaS + 4 CO (done with heat)

BaS + CaCl2 → BaCl2 + CaS (done by fusion of the mixture)

The BaCl2 can then be leached out from the mixture with water.

Uses

As a cheap, soluble salt of barium, barium chloride finds wide application in the laboratory. Most commonly it is used as a test for sulfate ion (see chemical properties above). It can be used to prepare other insoluble salts such as the oxalate by precipitation:

BaCl2(aq) + Na2C2O4(aq) → Ba2C2O4 (s) + 2 NaCl(aq)

Precautions

Highly toxic- 0.8-0.9g is fatal.
