What is LiI? Important Knowledge about LiI

  1. Definition of LiI
    LiI, also known as lithium iodide, is a chemical compound of lithium and iodine. In English, this substance is called Lithium iodide. The molecular structure of LiI includes one atom of lithium and one atom of iodine, along with atomic weights of 6.941 and 126.90447 atomic mass units respectively. This compound is formed by the electron transfer from the lithium atom to the iodine atom, resulting in the ionic structure of Li+ and I-.

  2. Properties of LiI
    LiI is stable, colorless crystals in solid form. LiI has no smell, salty taste, and neutral PH value. When heated, LiI turns into light purple vapor. In chemistry, LiI is very soluble in water and organic solvents and has the ability to react with many other substances such as metals, acids, non-metals, and salts.

  3. Common chemical equations with LiI
    Examples of chemical reactions with LiI are plentiful and diverse. LiI can react with metals such as sodium to form Li2 and NaI. In an acidic environment, LiI reacts with hydrochloric acid to form H2 and LiCl. With non-metals, LiI can react with chlorine to form LiCl and I2. With salts, LiI can react with NaCl to form NaI and LiCl.

  4. Synthesis of LiI
    LiI can be synthesized in the laboratory from lithium metal and iodine, or from lithium hydroxide and iotic acid. On an industrial scale, LiI is typically produced from the reaction between lithium hydroxide and iotic acid.
