Pyroboric acid, also known as tetraboric acid, is a chemical compound with the formula H2B4O7. Its name may seem daunting at first glance, but its spelling can be broken down using the International Phonetic Alphabet. "Pyro" is pronounced /ˈpaɪroʊ/, "boric" is pronounced /ˈbɔːrɪk/, and "acid" is pronounced /ˈæsɪd/. Therefore, "pyroboric acid" is pronounced /ˈpaɪroʊˈbɔːrɪk ˈæsɪd/. This acid is commonly used in laboratory and industrial settings as a cleaning and buffering agent due to its unique chemical properties.
Pyroboric acid is a chemical compound with the molecular formula HBO2. It is also known by its systematic name, orthoboric acid, or by its most common alternate name, metaboric acid. Pyroboric acid is a white, odorless solid that is highly soluble in water. It is an important compound in various industries and scientific applications.
Pyroboric acid is formed by heating or dehydrating orthoboric acid, H3BO3. The process involves driving off water molecules from orthoboric acid, resulting in a condensation reaction that forms pyroboric acid. The resulting compound has a simplified structure of B2O3H2, indicating the loss of water molecules.
Pyroboric acid is widely used as a precursor in the manufacturing of borate compounds. It is employed in the production of glass, ceramics, and enamel, as it acts as a fluxing agent, lowering the melting point of these materials and enabling them to flow more easily during their formation. Additionally, pyroboric acid is utilized in metallurgy, where it functions as a corrosion inhibitor and as a cleaning agent for metal surfaces.
In research laboratories, pyroboric acid finds application as a buffering agent, helping maintain the appropriate pH levels of solutions. It can also be used as a catalyst in certain organic reactions. Despite its importance in various industries, pyroboric acid should be handled with care due to its potential irritant and corrosive properties.

The word "pyroboric acid" is derived from the combination of two terms: "pyro-" and "boric acid".
1. "Pyro-" is a prefix derived from the Greek word "pyr", which means "fire". In scientific and chemical terminology, "pyro-" is often used to indicate heat or high temperatures.
2. "Boric acid" refers to a compound composed of the chemical element boron, oxygen, and hydrogen (H3BO3). Boric acid is commonly used as an antiseptic, insecticide, or as a precursor in the production of other chemical compounds.
Therefore, the term "pyroboric acid" suggests an acidic compound related to boron that might be formed or obtained at high temperatures. It is important to note that "pyroboric acid" is an outdated term and is not commonly used in contemporary chemistry.
