What is LiF? Important Knowledge about LiF

Definition of LiF:
LiF, or Lithium Fluoride, is a chemical substance belonging to the category of salts, formed from lithium ion (Li+) and fluoride (F-).
1.1 Common name: Lithium Fluoride
1.1.2 English name: Lithium Fluoride
1.2 Atomic structure: Comprises 1 atom of Lithium and 1 atom of Fluorine
1.3 Atomic mass: 25.939 (in Dalton units)
1.3.1 Molecular structure: LiF
1.4 Ion structure: Li+ and F-

Properties of LiF:
2.1 Physical properties of LiF: LiF is solid at room temperature, white in color, odorless and does not possess a pH level.
2.2 Chemical properties of LiF: LiF is insoluble in water and quite stable in the chemical environment. It resists strong acids like HCl, H₂SO₄, with its only weakness being solubility in HF acid.

Common chemical equations involving LiF:

• Reaction with metals: LiF + 2Na -> 2Li + NaF
• Reaction with acids: LiF + H₂SO₄ -> LiSO₄ + HF
• Reaction with nonmetals: LiF + Cl₂ -> LiCl + F₂

Synthesis of LiF:
4.1 Laboratory synthesis of LiF: Li + F₂ -> LiF
4.2 Industrial synthesis of LiF: In industry, LiF is typically produced by reacting Lithium Carbonate with Hydrofloric acid.
