Barium Chloride - BaCl<sub>2</sub>

What is Barium Chloride?

Barium Chloride is an inorganic salt which arises due to the direct reaction of barium (Ba) and chlorine (Cl). It is also called Barium Muriate or Barium dichloride. It is a white solid which is water soluble, hygroscopic and gives slight yellow-green colour to flame. The chemical formula of Barium Chloride is BaCl2.

Uses of Barium Chloride (BaCl2)

  • Barium Chloride is used as a raw material to produce barium salt.
  • It is used in chlorine-alkali industries.
  • Used in the manufacturing of rubber.
  • It is widely used in oil refining.
  • It is used in papermaking industry.
  • It is used in the hardening of steel.
  • Used to purify brine solution.

Preparation of Barium Chloride

Industrially, it is obtained in two steps.

Step 1: From barium sulfate at high temperature

BaSO4 + 4 C → BaS + 4 CO

Step 2: From Barium sulfide

BaS + 2 HCl → BaCl2 + H2S

Chlorine can be used instead of hydrochloric acid.

It can also be obtained from barium carbonate or barium hydroxide.

Effects on Health

This compound is toxic when ingested. Magnesium sulfate (MgSO4) and Sodium sulfate (Na2SO4) are probable antidotes as they form BaSO4 (barium sulfate). BaSO4 is comparatively non-toxic due to its insolubility.
