What is NF3? Important knowledge about NF3

  1. Definition of NF3
    NF3, also known as Nitrogen trifluoride in English, is a colorless, odorless chemical compound belonging to group 7A of the periodic table. This compound consists of one nitrogen atom and three fluorine atoms. The molar mass of NF3 is 71.00 g/mol. The combination of these atoms forms the NF3 molecule with a round pyramid structure, where nitrogen is at the center and surrounded by three fluorine atoms. NF3 does not form ions under normal conditions.

  2. Properties of NF3
    NF3 is gaseous at room temperature, colorless, and odorless. NF3 does not have acidic properties so it is impossible to measure its pH level. A unique chemical property of NF3 is its ability to react with water to form HF and N2O.

  3. Common chemical equations of NF3
    NF3 can react with metals, acids, non-metals, and salts. However, this reaction only occurs at high temperatures. Some practical examples can be NF3 + 3H2 -> NH3 + 3HForNF3 + 3Na.

  4. Synthesis of NF3
    In the laboratory, NF3 can be synthesized from N2 and F2 at high temperatures. In industry, NF3 is usually produced from ammonia and fluorine through displacement reactions, followed by a distillation process to separate NF3 from by-products.
