- Define BH3
BH3, also known as borane, is a chemical compound of boron and hydrogen. In English, it is called borane. BH3 has a molecular weight of 13.83 g/mol. The molecular structure of BH3 consists of one boron atom linked to three hydrogen atoms. BH3 does not form ions.
- Characteristics of BH3
2.1 Physical properties of BH3
BH3 is a gas in its normal form. This substance is colorless and odorless. It is not acidic, so the pH cannot be determined.
2.2 Chemical properties of BH3
BH3 is a fairly reactive substance. It can react with air, forming B2H6 and B(OH)3. It can also react with water, forming boron, hydrogen, and boronic acid.
- Common chemical equations of BH3
BH3 does not react with metals, acids, or non-metals. However, it can react with salts. For example:
2 BH3 + 6NaCl -> 2BCl3 + 3H2 + 6Na
- Synthesis of BH3
4.1 Laboratory synthesis of BH3
There are a few ways to synthesize BH3 in the laboratory, such as the reaction of boron trichloride with hydrogen:
4.2 Industrial synthesis of BH3
On an industrial scale, BH3 is typically produced from the reaction of borax with sulfuric acid, then reduced with hydrogen:
