What is SnBr4? Important knowledge about SnBr4.

  1. Definition of SnBr4
    SnBr4, also known as stannic bromide or Tin(IV) bromide in English, is a chemical substance with the molecular formula SnBr4. It consists of one tin atom (Sn) and four bromine atoms (Br). Its molar mass is 438.33 g/mol. It exists as ions with Sn having an oxidation number of +4 and Br having an oxidation number of -1.

  2. Properties of SnBr4:
    2.1 Physical properties of SnBr4
    SnBr4 is a solid substance, white in color and odorless. Its pH is not determined as it is a water-insoluble solid.
    2.2 Chemical properties of SnBr4
    SnBr4 reacts with water to form SnO2 and HBr. It also reacts with alkali metals to form the respective bromide salts.

  3. Common chemical equations of SnBr4
    SnBr4 reacts with alkali metals such as Na, K to form bromide salts like NaBr, KBr.
    SnBr4 + 4Na -> Sn + 4NaBr
    SnBr4 + 4K -> Sn + 4KBr
    In acidic environment, SnBr4 forms HBr:
    SnBr4 + H2O -> SnO2 + 4HBr
    SnBr4 does not react with non-metals and salts.

  4. Preparation of SnBr4
    4.1 Laboratory preparation of SnBr4
    SnBr4 can be prepared by reacting Br2 with Sn:
    Sn + 2Br2 -> SnBr4
    4.2 Industrial preparation of SnBr4
    SnBr4 is not produced on an industrial scale as it lacks widespread applications in the industry.
