Barium iodide is an ionic compound that is white in colour and is soluble in acetone and water. Its molecular formula is BaI2(H2O)2.
It is used in the preparation of iodide compounds, which are inorganic compounds of iodine. The barium iodide hydrate form is easily obtainable.
In addition to its uses in the preparation of iodide, it also has a small number of other applications. One of them is radioactive barium in-situ. Other uses are in the manufacture of organic compounds. However, it is not widely used in medicine and research.
In contrast, barium sulfate is a widely used agent in diagnostic imaging. This substance is injected into veins to enhance images of blood vessels and organs. Sometimes it is administered by mouth, or through enema.
While iodine-based and barium-based contrast agents are often used for similar purposes, they can be distinguished in many ways. In particular, iodine-based contrast agents attenuate x-rays, while barium-based contrast agents do not.
Iodine is a halogen, which means that it accepts an electron from a metal. The iodine ion then accepts two electrons to create an octet electronic configuration. That is why it has a negative charge.
The iodine ion is also essential for the formation of certain organic compounds. Therefore, it is important to understand the structure and properties of this halogen. Similarly, the elements that make up barium are also important to know.
Barium-based contrast agents are typically given as a finely pulverized powder slurry. Usually, the patient is positioned enema-style, so that the barium sulfate dissolves into the abdomen.
