What is BaF2? Important knowledge about BaF2.

  1. Definition of BaF2
    BaF2, also known as Barium Fluoride, is a chemical compound from Barium (Ba) and Fluoride (F). The molecular weight of BaF2 is 175.3396 g/mol. The molecular structure of BaF2 consists of 1 Barium atom combined with 2 Fluorine atoms, forming the BaF2 molecule. The ionic structure of BaF2 includes Ba2+ ion and two F- ions.

  2. Properties: BaF2
    2.1 Physical properties: BaF2 is a solid, colorless or white in color. It has no distinct smell. The pH level of BaF2 solution under standard conditions depends on its concentration in the solution.
    2.2 Chemical properties: BaF2 is insoluble in water and can react with strong acids to produce regular fluoride and barium ions.

  3. Common chemical equations:
    BaF2 can react with sulfuric acid H2SO4 to produce BaSO4 and HF. It can also react with hydrochloric acid HCL to produce BaCl2 and HF.

  4. Synthesis of BaF2
    4.1 Laboratory synthesis: BaF2 is usually not synthesized in the laboratory due to the challenging control of the chemical properties of fluorine.
    4.2 Industrial synthesis: On an industrial scale, BaF2 is typically produced from the reaction of barium carbonate with hydrofluoric acid:
    BaCO3 + 2HF -> BaF2 + CO2 + H2O
