Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula B(OH) 3. It may also be called hydrogen orthoborate , trihydroxidoboron or boracic acid . [ 3 ]
Boric is a chemistry term that refers to substances containing boron, such as: boric acid or orthoboric acid, B(OH) 3; metaboric acid, an acid containing boron, HBO 2; tetraboric acid or pyroboric acid, an acid containing boron, H 2 B 4 O 7; boric oxide, specifically boron trioxide B 2 O 3; a boric ester, or organic borate; Boric may also refer to:
Tetraboric acid or pyroboric acid is a chemical compound with empirical formula H 2 B 4 O 7. [2] It is a colourless water-soluble solid formed by the dehydration or polymerization boric acid. Tetraboric acid is formally the parent acid of the tetraborate anion [B 4 O 7] 2−.
Borax "dihydrate" has the formula Na 2 B 4 O 7 ·2H 2 O, which is actually anhydrous, with the correct formula Na 2 B 4 O 5 (OH) 4. It can be obtained by heating the "decahydrate" or "pentahydrate" to above 116-120 °C. [20] Anhydrous borax is sodium tetraborate proper, with formula Na 2 B 4 O 7. It can be obtained by heating any hydrate to 300 ...
Potassium fluoroborate is obtained by treating potassium carbonate with boric acid and hydrofluoric acid. B(OH) 3 + 4 HF → HBF 4 + 3 H 2 O 2 HBF 4 + K 2 CO 3 → 2 KBF 4 + H 2 CO 3. Fluoroborates of alkali metals and ammonium ions crystallize as water-soluble hydrates with the exception of potassium, rubidium, and cesium.
The main forms of metaboric acid are: Modification III, or trimeric, with the molecular formula H 3 B 3 O 6. The molecule has C 3h symmetry, with a six-member ring of alternating boron and oxygen atoms at the core, with OH groups attached to the borons. The crystal structure is orthorhombic with a sheet-like structure, similar to that of boric ...

Boranes are chemical compounds of boron and hydrogen, with the generic formula of B x H y. These compounds do not occur in nature. Many of the boranes readily oxidise on contact with air, some violently. The parent member BH 3 is called borane, but it is known only in the gaseous state, and dimerises to form diborane, B 2 H 6. The larger ...
