Boric acid is a weak acid, with pK a (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of 9.24 in pure water at 25 °C. But apparent p K a is substantially lower in swimming pool or ocean waters because of interactions with various other molecules in solution.

Borax is also easily converted to boric acid and other borates, which have many applications. Its reaction with hydrochloric acid to form boric acid is: Na 2 B 4 O 7 ·10H 2 O + 2 HCl → 4 H 3 BO 3 + 2 NaCl + 5 H 2 O. Borax is sufficiently stable to find use as a primary standard for acid-base titrimetry. [17]: p.316
Boric acid has antiseptic, antifungal, and antiviral properties and, for these reasons, is applied as a water clarifier in swimming pool water treatment. [130] Mild solutions of boric acid have been used as eye antiseptics. [citation needed] Bortezomib (marketed as Velcade and Cytomib). Boron appears as an active element in the organic ...
In aqueous solution, boric acid B(OH) 3 can act as a weak Brønsted acid, that is, a proton donor, with pK a ~ 9. However, it more often acts as a Lewis acid, accepting an electron pair from a hydroxide ion produced by the water autoprotolysis: [11] B(OH) 3 + 2 H 2 O ⇌ [B(OH) 4] − + H 3 O + (pK = 8.98) [12]
Boric is a chemistry term that refers to substances containing boron, such as: boric acid or orthoboric acid, B(OH) 3; metaboric acid, an acid containing boron, HBO 2; tetraboric acid or pyroboric acid, an acid containing boron, H 2 B 4 O 7; boric oxide, specifically boron trioxide B 2 O 3; a boric ester, or organic borate; Boric may also refer to:
Boric acid is an antiseptic used as a vaginal medication to treat vaginal infections including yeast infections, bacterial vaginosis, and trichomoniasis. [5] [2] It is administered as a capsule or suppository inserted into the vagina. [2] [6] The compound is not a pharmaceutical drug and is instead available over-the-counter.
Some of the anhydrous borates above can be crystallized from molten mixtured of sodium oxide and boric oxide. [6] Some sodium borates hower cannot be analyzed as combinations xNa 2 O·yB 2 O 3 ·zH 2 O of the three ordinary oxides. The most important example is sodium perborate, originally described as NaBO 3 ·H 2 O but actually (Na +) 2 [B 2 ...
