Acid, boracic boric

Boric acid (boracic acid) [10043-35-3] M 61.8, m 171 , pK 9.23. Crystd three times from H2O (3mL/g) between 100° and 0°, after filtering through sintered glass. Dried to constant weight over metaboric acid in a desiccator. It is steam volatile. After 2 recrystns of ACS grade it had Ag at 0.2 ppm. 

Boric acid (boracic acid H BO ) is used for the manufacture of glass, welding, mattress batting, cotton textiles, and a weak eyewash solution. 

After the chemical revolution, sedative salt came to be regarded as an acidic oxide, boric (or boracic) acid. Even at the close of the eighteenth century, its chemical nature was not understood. In a letter to the Annales de Chimie et de F ysiqtie, A. N. Scherer wrote in 1799 I have just been assured that Crell has recognized carbon as the radical of boracic acid (67).

Before regarding their proof as complete, Gay-Lussac and Thenard wished not only to decompose boric acid, but to recompose it. On November 30 of the same year they were able to state m the Annales de Chimie et dc Physique that the composition of boracic acid is no longer problematical. In fact, said they, we decompose and we recompose this acid at will Their method was as follows ...

Thenard and Gay-Lussac found a new way to separate boron from its compounds. They heated boracic acid (also known as boric acid, H3BO3) with potassium metal to produce impure boron. Thenard and Gay-Lussac were given credit for discovering the new element. In 1892, French chemist Henri Moissan (1852—1907) produced boron that was 98 percent pure.

In 1702 Homberg prepared the free acid from borax and called it sal sedativum. In 1747 Baron discovered that borax is a compound of soda and sal sedativum in other words, it is a salt and with the establishment of Lavoisier s system of nomenclature, introduced in conjunction with de Morveau, Berthollet, and Fourcroy in 1787, the incorrect appellation sal sedativum gave place to boracic add, subsequently shortened to boric acid. Lavoisier regarded it as an oxide. The news reaching Paris early in 1808 that Davy had, in the previous October, isolated the alkali metals potassium and sodium stimulated chemists generally to attempt the isolation of other metals. Gay-Lussac and Thenard prepared potassium that year (1808) by a new process, namely heating potash with metallic iron, a method which Davy himself subsequently adopted as more convenient than his own electrolytic one. The potassium was now heated with boric anhydride in a copper tube and, after cooling,... 

German chemist Wilhelm Homberg discovers boracic or boric acid. 

Orthoboric acid, also called boracic or boric acid, is usually made by precipitation from a solution of borax on treatment with sulfuric acid. The acid is a solid at room temperature and is only sparingly soluble in water. Dilute aqueous solutions are often used as mild antiseptics. Orthoboric acid is a very weak Lewis acid that, on reaction with water, produces hydronium ions as follows ...
