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 Use of Barium Chloride
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
Toxicity of Barium Chloride
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.
