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