Metaborate Chemical

In aqueous solution borate exists in many forms. In acid and near-neutral conditions, it is boric acid, commonly written as H3BO3 but more correctly B(OH)3. The pKa of boric acid is 9.14 at 25°C. Boric acid does not dissociate in aqueous solution, but is acidic due to its interaction with water molecules, forming tetrahydroxyborate:

Lithium metaborate a mixture of both, can be used in borate fusion sample prepration of various samples for analysis by XRF, Atomic Adsorption,

Borates are chemical compounds which contain oxoanions of boron in oxidation state +3. The simplest borate ion, BO33−, has a trigonal planar structure. Other borates are made up of trigonal BO3 or tetrahedral BO4 structural units, sharing oxygen atoms.[1] Boron occurs in nature mainly as as borate minerals and borosilicates.
