Barium Iodide Dihydrate

Barium iodide dihydrate is a chemical compound with the molecular formula BaI2·2H2O. It consists of barium cations (Ba2+) and iodide anions (I-) held together by ionic bonds, along with two water molecules (H2O) per formula unit that are hydrogen bonded to the compound.

Barium iodide dihydrate is a white crystalline solid that is soluble in water but insoluble in most organic solvents. It has a melting point of 673 °C and a density of 4.93 g/cm3.

In terms of its uses, barium iodide dihydrate is primarily employed as a reagent in organic synthesis, as well as in radiography and fluorescent imaging applications. It can also be used as a scintillation material for detecting gamma rays and neutrons.

It is important to handle barium iodide dihydrate with care, as it is toxic if ingested or inhaled. Protective clothing, gloves, and eyewear should be worn when working with this compound, and it should only be used in a well-ventilated area.
