Boric acid predominates in solution below pH 9 Boric acid buffers against rising pH in swimming pools. Boric acid in equilibrium with its conjugate base the borate ion is widely used (in the concentration range 50–100 ppm boron equivalents) as a primary or adjunct pH buffer system in swimming pools.
In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction
When some strong acid is added to an equilibrium mixture of the weak acid and its conjugate base, hydrogen ions (H +) are added, and the equilibrium is shifted to the left, in accordance with Le Chatelier's principle. Because of this, the hydrogen ion concentration increases by less than the amount expected for the quantity of strong acid added.
In animals, boric acid/borate salts are essentially completely absorbed following oral ingestion. Absorption occurs via inhalation, although quantitative data are unavailable. Limited data indicate that boric acid/salts are not absorbed through intact skin to any significant extent, although absorption occurs through skin that is severely abraded.

A broader definition of acid dissociation includes hydrolysis, in which protons are produced by the splitting of water molecules. For example, boric acid, B(OH) 3, acts as a weak acid, even though it is not a proton donor, because of the hydrolysis equilibrium B(OH) 3 + H 2 O ⇌ B(OH) − 4 + H +. Similarly, metal ion hydrolysis causes ions ...
Triethyl borate is a colorless liquid with the formula B(OCH 2 CH 3) 3. It is an ester of boric acid and ethanol. It has few applications. [1] It is a weak Lewis acid (AN = 17 as measured by the Gutmann–Beckett method). [2] It burns with a green flame and solutions of it in ethanol are therefore used in special effects and pyrotechnics.
Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...
