Barium Iodide, Formula, Chemical Properties, Preparation, Uses

Barium Iodide

Barium iodide is an inorganic compound that has the combination of barium and iodine. It is an ionic compound because it is able to accept the electronic configuration of the atoms. This has been accepted by the donating the electrons to the ionic substances. Barium iodide is soluble in water and insoluble in acetone and methanol. It could be the change of paking in the anhydrous form. The systematic IUPAC name is known as Barium iodide. The chemical or molecular formula of Barium iodide is Bal2.

Structural Formula

This is the structural formula of the Barium iodide:

Barium Iodide

Chemical Formula

The chemical formula of the Barium iodide is Bal2.

Preparation Method

When the barium metal is reacted with the 1,2- diiodoethane in ether it forms the barium iodide. Further it is reacted with the alkyl potassium compounds to form the organobarium compounds. The organobarium is a carbon bonded to bond with the any 2 group of elements. It is widely used in the organic chemistry. If you want the barium metal, then it is highly active with the lithium biphenyl compound to reduced.
