Lithium Iodide Formula

Lithium Iodide Formula

An inorganic compound in which lithium and iodine combine to form lithium iodide. Also, iodide is oxidised to form iodine, which is easily identified by its colour change from white to yellow in the air. In addition, it can exist in different hydrated forms such as monohydrate, dihydrate, and trihydrate. Additionally, lithium iodide crystallises with a sodium chloride motif (NaCl motif). See Lithium Iodide Formula Extramarks.

Lithium Iodide Properties

Lithium Iodide Formula has the chemical formula Li, and its molar mass or molecular weight is 133.85 g/mol. The lithium cation (Li+) reacts with the iodine anion (I-) to form lithium iodide, a white crystalline solid with a melting point of 446-469 °C and a boiling point of 1170-1190 °C. Furthermore, its density is 4.08 g/cm3, indicating that it is solid at room temperature.

It is also soluble in water, methanol, alcohol, and acetone, and well soluble in an aqueous ammonia solution. Moreover, its heat capacity is 54.4 J/mol K or 0.381 J/g K and its magnetic susceptibility is -50 x 10 -6 cm3/mol. Its refractive index is 1.955.

Lithium Iodide Uses

Lithium iodide is used as the electrolyte for high temperature batteries. It is also used for the long-life batteries required for artificial heart pacemakers. It is also fixed and used as a phosphor for neutron detection. It is also used as a complex with iodide in the electrolyte of dye-sensitized solar cells. LiI (lithium iodide) is also useful in organic synthesis for breaking C-O bonds. For example, it can be used to convert a methyl ester to a carboxylic acid.


Additionally, equivalent reactions are associated with epoxides and aziridines. I also use lithium iodide as an X-ray contrast agent for CT scans, but I have stopped using it due to nephrotoxicity. Additionally, inorganic iodide solutions suffer from high viscosity and high osmolarity. However, current iodinated contrast agents are organic iodine compounds.
