Borataanion
Borataanion, commonly referred to as the borate ion, is the class of anions derived from boric acid (H3BO3) by deprotonation and/or condensation of boron-oxygen units. In aqueous solution, the most prevalent species is the tetrahydroxyborate ion, B(OH)4−, formed when boric acid reacts with hydroxide: B(OH)3 + 2 H2O ⇌ B(OH)4− + H3O+. This monoanion dominates in neutral to mildly basic solutions and represents the main borate form under many laboratory conditions.
In more concentrated or strongly basic environments, borate units can condense into polyborate anions. The exact
Preparation and occurrence: Borate species arise from boron-containing materials such as boric acid or borates used
Applications and relevance: Borate buffers provide stability around pH 9–10 and are widely used in biochemistry
Note: The term boratanion is largely synonymous with borate ion; specific names such as orthoborate or tetraborate
