Chemical and Physical Properties

Barium chloride forms white odourless crystals with a bitter salty taste, soluble in water and methanol, but insoluble in ethanol and acetone. Its boiling point is 1560°C and melting point is 961°C.

Uses and Applications

As an inexpensive soluble salt, barium chloride has many different applications, including:

  • Commonly used as a test to detect the presence of sulphate, as it produces a precipitate of barium sulphate (BaSO4).
  • Used in industrial settings in the purification of brine in caustic chlorine plants
  • Used in case hardening steel
  • Used in the manufacture of certain pigments
  • Used in the synthesis of barium salts
  • Used in fireworks to give a green colouration
  • Used in the treatment of impaction in horses. This is usually seen as a last resort as it carries a high risk of fatal cardiac arrest


Similar to other water-soluble barium salts, barium chloride can be extremely toxic. In cases of ingestion, magnesium sulphate (MgSO4) or sodium sulphate (NaSO4) can be used as antidotes as they react with BaCl2 to form insoluble barium sulphate (BaSO4). This compound is also toxic, but its detrimental effects can be more easily controlled due to its insolubility.

The Most Common Salt of Barium

Barium chloride (BaCl2) is the most common of barium's salts. It forms white crystals that are odourless, hygroscopic and soluble in water. Another characteristic of barium chloride is that it produces a yellow-green flame when burned.

This compound can be synthesised from barium carbonate (BaCO3) and barium hydroxide (Ba(OH)2) in the presence of hydrochloric acid (HCl). However, the most common process used in the industry involves a two-step process.

Starting with barium sulphate (BaSO4), the first reaction produces barium sulphide (BaS), which is then added to calcium chloride (CaCl2) to produce barium chloride.

A Colourful Application

Its toxicity means that barium chloride has limited applications, but it does have one rather colourful use: it is used to generate the colour green in fireworks.

This compound is also used:

  • To test for sulphate in the lab
  • In the synthesis of other barium salts
  • In the manufacture of pigments at an industrial level

Toxic compound

Like all other barium slats, barium chloride is a highly toxic component if swallowed. Antidotes include magnesium sulphate and sodium sulphate, which form barium sulphate (BaSO4). This compound is also toxic, but less because it is insoluble.

Barium ions are also toxic for marine life, so disposal must always follow strict procedures. Full details can be found on the Material Safety Data Sheet.
