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 (also referred to as sodium borate, tincal (/ ˈtɪŋkəl /) and tincar (/ ˈtɪŋkər /)) is a salt (ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na 2 H 20 B 4 O 17 (also written as Na 2 B 4 O 7·10H2O[1][a]). It is a colorless crystalline solid that dissolves in water to make a basic solution.
Boric acid will initially decompose into steam, (H 2 O (g)) and metaboric acid (HBO 2) at around 170 °C, and further heating above 300 °C will produce more steam and diboron trioxide. The reactions are: H 3 BO 3 → HBO 2 + H 2 O 2 HBO 2 → B 2 O 3 + H 2 O. Boric acid goes to anhydrous microcrystalline B 2 O 3 in a heated fluidized bed. [21 ...
v. t. e. 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. known as dissociation in the context of acid–base reactions. The chemical species HA is an ...
t. e. The Brønsted–Lowry theory (also called proton theory of acids and bases[1]) is an acid–base reaction theory which was first developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry independently in 1923. [2][3] The basic concept of this theory is that when an acid and a base react with each other, the acid forms its conjugate ...
Boric acid has antiseptic, antifungal, and antiviral properties and, for these reasons, is applied as a water clarifier in swimming pool water treatment. [139] Mild solutions of boric acid have been used as eye antiseptics. Bortezomib (marketed as Velcade and Cytomib). Boron appears as an active element in the organic pharmaceutical bortezomib ...
Sodium borate. Sodium borate is a generic name for any salt of sodium with an anion consisting of boron and oxygen, and possibly hydrogen, or any hydrate thereof. It can be seen as a hydrated sodium salt of the appropriate boroxy acid, although the latter may not be a stable compound. Many sodium borates have important industrial and household ...
Borate. A borate is any of a range of boron oxyanions, anions containing boron and oxygen, such as orthoborate BO3− 3, metaborate BO− 2, or tetraborate B4O2− 7; or any salt of such anions, such as sodium metaborate, Na+[BO2]− and borax (Na+)2[B4O7]2−. The name also refers to esters of such anions, such as trimethyl borate B (OCH3)3 ...
