Introduction to Barium Iodide

The compound known as Barium iodide ₂ (Bal2) is derived from the decomposition of barium using metallic sodium . This substance forms small, colorless needle-like crystals that have a slight deliquescence and dissolve readily in water. The element barium, whose name originates from the Greek word "barys" meaning "heavy," is a heavy metal first isolated by Sir Humphry Davy in 1808 through the electrolysis of molten barium salts. Barium iodide is produced by combining hydroiodic acid with a solution of barium hydroxide or barium carbonate.

IUPAC name – barium(2+) diiodide

Chemical Characteristics of Barium Iodide – BaI ₂

• When barium iodide is mixed with potassium bromide, it forms a yellow precipitate of potassium iodide and barium bromide.
• When barium iodide is combined with sodium sulphate , it forms barium sulphate. The chemical equation for this reaction is as follows:

BaI ₂ + Na ₂ SO ₄ → BaSO ₄ + NaI

Applications of Barium Iodide – BaI ₂

• Utilized in the production of barium dioxide, but it is not used for medicinal purposes.
• Employed in the creation of other iodide compounds.
• Used to increase the density of copper castings, as described in a paper presented to the Electrochemical Society.
