What is SF6? Important knowledge about SF6.

  1. SF6 Definition:
    1.1 The common name for this substance is Sulfur Hexafluoride.
    1.2 SF6 consists of 1 Sulfur atom and 6 Fluorine atoms.
    1.3 The atomic weight of SF6 is 146.06. The SF6 molecule has a cubic crystal structure, with the Sulfur atom at the center and 6 Fluorine atoms surrounding to form a cubic shape.
    1.4 SF6 does not form ions under normal conditions as it is a non-polar substance.

  2. Properties of SF6:
    2.1 Physical properties: SF6 in gas state is colourless and odourless. Its pH value can’t be measured because it is not a liquid or solid.
    2.2 Chemical properties: SF6 rarely participates in chemical reactions due to its stable structure.

  3. Common Chemical Equations Involving SF6:
    Given its unique chemical properties, SF6 rarely participates in chemical reactions. Therefore, there are no examples of its reactions with metals, acids, non-metals or salts.

  4. Preparation of SF6:
    4.1 Laboratory preparation of SF6: SF6 can be prepared from Sulfur and Fluorine according to the equation: S + 3F2 -> SF6.
    4.2 Industrial preparation of SF6: In industry, SF6 is commonly produced by the electrolysis of HF solution in the presence of Sulfur.
