What is B2O? Important Knowledge about B2O

  1. Definition of B2O
    B2O, also known as Boron Oxide, is a chemical substance with the formula B2O3. In English, it is referred to as Boron Oxide. This substance has an atomic mass of 43.62 and a molecular weight of 69.62. The B2O3 molecule consists of 2 boron atoms and 3 oxygen atoms. As a strong acid oxide, B2O3 forms the ion [BO3]3- in solution.

  2. Properties: B2O
    B2O has physical properties as a white crystalline solid, odorless, and has a low pH level. The chemical properties of B2O indicate that it reacts with water to form boric acid.

  3. Common chemical equations
    B2O does not react with metals, acids, and non-metals. The main reaction of B2O is with water:
    B2O3 + 3H2O -> 2H3BO3

  4. Preparation of B2O
    In the laboratory, B2O can be prepared by heating borax:
    4Na2B4O7 + 7H2SO4 + 22H2O -> 4Na2SO4 + 2B2O3 + 21H2O
    In industry, B2O is produced by heating borax with sulfuric acid:
    Na2B4O7.10H2O + H2SO4 -> B2O3 + Na2SO4 + H2O
    Or by heating Boron in the air
    4B + 3O2 -> 2B2O3.
