What is Li2WO4? Important knowledge about Li2WO4.

1. Definition of Li₂WO₄

Li₂WO₄, or Lithium Tungstate, is a colorless compound of lithium and tungsten. In the formula Li₂WO₄, we see 2 lithium atoms, 1 tungsten atom, and 4 oxygen atoms.

The atomic mass of lithium is 6.94 atomic mass units, of tungsten is 183.84, and of oxygen is 16. This shows that the atomic mass of Li₂WO₄ is 287.76.

The ionic structure of Li₂WO₄ consists of 2 positive lithium ions and 1 negative tungstate ion. In the tungstate ion, the tungsten atom is bonded with 4 oxygen atoms to form a polyatomic ion.

2. Properties of Li₂WO₄

Li₂WO₄ is mainly a colorless, odorless white solid with a neutral PH. It is insoluble in water but can dissolve in acid.

The chemical properties of Li₂WO₄ relate to its interactions with other substances. It can react with strong acids to produce lithium ions and tungstate ions.

3. Chemical Equation of Li₂WO₄

Li₂WO₄ is mainly used in reactions with acids. For example, when reacting with sulfuric acid, Li₂WO₄ will produce H₂SO₄ and Li₂SO₄. In addition, it can also react with nonmetals like chlorine to form LiCl and WO₃.

4. Synthesis of Li₂WO₄

Li₂WO₄ is usually synthesized in the laboratory by combining lithium and tungsten in an acidic environment. Industrially, it is produced by heating lithium and tungsten at high temperatures.
