Borate ions occur, alone or with other anions, in many borate and borosilicate minerals such as borax, boracite, ulexite (boronatrocalcite) and colemanite. Borates also occur in seawater, where they make an important contribution to the absorption of low frequency sound in seawater. [1] Borates also occur in plants, including almost all fruits. [2]
Borax as a source of borate has been used to take advantage of the co-complexing ability of borate with other agents in water to form complex ions with various substances. Borate and a suitable polymer bed are used to chromatograph non-glycated hemoglobin differentially from glycated hemoglobin (chiefly HbA1c), which is an indicator of long ...
The Borate Minerals are minerals which contain a borate anion group. The borate (BO 3 ) units may be polymerised similar to the SiO 4 unit of the silicate mineral class. This results in B 2 O 5 , B 3 O 6 , B 2 O 4 anions as well as more complex structures which include hydroxide or halogen anions. [ 2 ]
Boric acid in equilibrium with its conjugate base the borate ion is widely used (in the concentration range 50–100 ppm boron equivalents) as a primary or adjunct pH buffer system in swimming pools. Boric acid is a weak acid, with p K a (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of ...
Structure of the hydrated tetraborate (borax) ion, [B 4 O 5 (OH) 4] 2−. In chemistry, tetraborate or pyroborate is an anion (negative ion) with formula B 4 O 2− 7; or a salt containing that anion, such as sodium tetraborate, Na 2 B 4 O 7. It is one of the boron oxoacids, that is, a borate.
People are ingesting borax. Also known by its chemical name sodium borate decahydrate, borax is a salt typically used to kill ants and boost laundry detergent, among other household cleaning needs ...
Borax (Na 2 B 4 O 5 (OH) 4 · 8 H 2 O [2]) is a borate mineral found in evaporite deposits of alkaline lacustrine environments and as a surface efflorescence in arid regions. It is the chief mineral mined from the deposits at Boron, California and nearby locations, and is the chief source of commercial borax.
