硼酸盐

硼酸盐是一类含硼的化合物。当中的硼可以与三个氧原子键合成B(OR)3，也可以与四个氧原子键合成B(OR)4阴离子。

硼酸根离子的化学式为BO3。它可与金属元素形成盐。在自然界中所发现的硼通常为硼酸盐矿物。硼也会与硅酸盐结合形成络合硼硅酸盐矿物例如电气石。

硼酸盐以许多形式存在。在酸和近中性的环境上，它是硼酸（通常写成H3BO3，但B(OH)3更为正确）。硼酸在25°C的 pKa为9.14，硼酸虽不会在水溶液中分解，但它却是酸性，因它会与水分子产生相互作用，形成B(OH)4：

作为典型的多元酸，硼酸（H3BO3）可随pH值之上升，发布氢离子，而变成H2BO3、HBO3以至BO3。

Borate 硼酸盐

Idealized structure of a compound with trigonal planar molecular geometry.
The structure of the tetrahydroxyborate anion
Tetraborate (borax) ion structure: pink, boron; red, oxygen; white, hydrogen. This tetrameric boron structure comprises two boron atoms in tetrahedral configuration sharing one common oxygen atom and linked by other oxygens to two other boron atoms present in trigonal configuration. Three cycles are also visible: two with 3 boron atoms and one with 4 boron atoms.
borax crystals

Borates are the name for a large number of boron-containing oxyanions. The term "borates" may also refer to tetrahedral boron anions, or more loosely to chemical compounds which contain borate anions of either description. Larger borates are composed of trigonal planar BO3 or tetrahedral BO4 structural units, joined together via shared oxygen atoms and may be cyclic or linear in structure. Boron most often occurs in nature as borates, such as borate minerals and borosilicates.
