Ascorbate Mineral ascorbates are salts of ascorbic acid (aka vitamin C). They are powders manufactured by reacting ascorbic acid with mineral carbonates in aqueous solutions, venting the carbon dioxide, drying the reaction product, and then milling the dried product to the desired particle size. The choice of the mineral carbonates can be calcium carbonate, potassium carbonate, sodium bicarbonate, magnesium carbonate, or many other mineral forms. Ascorbates are highly reactive antioxidants used as food

Borate Borates in chemistry are chemical compounds containing boron bonded to three oxygen atoms written as B(OR) 3 . In B(OR) 4 - anions, this number increases to four. The borate ion is BO 3 3- . it forms salts with metallic elements. Boron found in nature is commonly as a borate mineral. Boron is also found combined with silicate to form complex borosilicate minerals such as the tourmalines. Borate exists in many forms. In acid and near-neutral conditions, it is boric acid, commonly wri

Tetra Borate Whatever cannot be saved for recovery or recycling should be managed in an appropriate and approved waste disposal facility. Processing, use or contamination of this product may change the waste management options. State and local disposal regulations may differ from federal disposal regulations. Dispose of container and unused contents in accordance with federal, state and local requirements Lithium Tetraborate Ventilation System A system of local and/or g

Penta Borate Even though boric acid adds hydroxide to form B(OH) 4 -, you may find for pKa values and other calculations, the fictitious ions are easier to use. Thus for a typical polyprotic acid, the deprotonation series dihydrogen borate [H 2 BO 3 -; ], hydrogen borate [HBO 3 2- ] and borate [BO 3 3- ] may be written as pH increases. Boric acid can be used to form many polymeric ions. The tetraborate ion, B 4 O 7 2- , is very common; the hydrogen tetraborate ion, HB 4 O 7- , as

Meta Borate In order to find the configuration of the metaborate group the crystal structure of potassium metaborate was determined. The crystals are rhombohedral ar = 7.76A, = 110° 36 with six molecules KBO2. The density is 2.348. The space group is R c(D3d 6 ). All atoms are lying on twofold axes at positions: ±(u, ½-u, ¼) . The parameters were determined by means of two-dimensional Fourier analyses Lithium Metaborate Compounds have different physical and chemical properties from their constituent elements. This is the one principal criterion for distinguishing a compound f
