Boron in Inorganic Chemistry: Its Properties and Applications
Introduction
Boron is a chemical element with the symbol B and atomic number 5. It is located in the second period and at the top of Group 13 (Group III according to the main group numbering) in the periodic table, classified as a main group element, and its group is named after it, the Boron Group.Boron belongs to the metalloid family and shares more chemical properties with silicon than with aluminum. Crystalline boron is chemically inert, resistant to hot hydrofluoric and hydrochloric acids, and shows no effect of phosphoric acid on boron except at temperatures above 600°C.
Inorganic Chemistry of Boron
Boron forms numerous inorganic compounds, characterized by their unique properties. Some of the most important inorganic boron compounds include:1. Boron Oxide: It is a boron-oxygen compound with the chemical formula B2O3. Boron oxide is a colorless, insoluble solid.
2B + 3O2 → B2O3
2. Boron Trioxide: It is a boron-oxygen compound with the chemical formula B2O3. Boron trioxide is a white, soluble solid.
B2O3 + H2O → 2B(OH)3
3. Boron Trifluoride: It is a boron-fluorine compound with the chemical formula BF3. Boron trifluoride is a colorless gas with a pungent odor.
B + 3F2 → BF3
4. Boron Trichloride: It is a boron-chlorine compound with the chemical formula BCl3. Boron trichloride is a colorless liquid with a pungent odor.
B + 3Cl2 → BCl3
5. Boron Tribromide: It is a boron-bromine compound with the chemical formula BBr3. Boron tribromide is a colorless liquid with a pungent odor.
B + 3Br2 → BBr3
