Overview

Boric acid, also called hydrogen borate, boracic acid, and orthoboric acid is a weak, monobasic Lewis acid of boron. However, some of its behaviour towards some chemical reactions suggest it to be tribasic acid in the Brønsted sense as well. Boric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other chemical compounds. It has the chemical formula H3BO3 (sometimes written B(OH)3), and exists in the form of colorless cr…

Occurrence

Boric acid, or sassolite, is found mainly in its free state in some volcanic districts, for example, in the Italian region of Tuscany, the Lipari Islands and the US state of Nevada. In these volcanic settings it issues, mixed with steam, from fissures in the ground. It is also found as a constituent of many naturally occurring minerals – borax, boracite, ulexite (boronatrocalcite) and colemanite. Boric acid and its salts are found in seawater. It is also found in plants, including almost all fruits.

Preparation

Boric acid may be prepared by reacting borax (sodium tetraborate decahydrate) with a mineral acid, such as hydrochloric acid:
Na2B4O7·10H2O + 2 HCl → 4 B(OH)3 + 2 NaCl + 5 H2O
It is also formed as a by product of hydrolysis of boron trihalides and diborane:
B2H6 + 6 H2O → 2 B(OH)3 + 6 H2

Properties

Boric acid is soluble in water. When heated above 170 °C, it dehydrates, forming metaboric acid (HBO2):
H3BO3 → HBO2 + H2O
Metaboric acid is a white, cubic crystalline solid and is only slightly soluble in water. Metaboric acid melts at about 236 °C, and when heated above about 300 °C further dehydrates, forming tet…

Reactions

With polyols containing cis-vicinal diols, such as glycerol and mannitol, the acidity of the boric acid solution is increased. With different mannitol concentrations, the pK of B(OH)3 extends on five orders of magnitude (from 9 to 4): this exacerbed acidity of boric acid in the presence of mannitol is also sometimes referred as "mannitoboric acid". Greenwood and Earnshawn (1997) refer to a pK value of 5.15 while a pK value of 3.80 is also reported in Vogel's book. This is due to the form…

Toxicology

Based on mammalian median lethal dose (LD50) rating of 2,660 mg/kg body mass, boric acid is only poisonous if taken internally or inhaled in large quantities. The Fourteenth Edition of the Merck Index indicates that the LD50 of boric acid is 5.14 g/kg for oral dosages given to rats, and that 5 to 20 g/kg has produced death in adult humans. For a 70 kg adult, at the lower 5g limit, 350g could produce death in humans. For comparison's sake, the LD50 of salt is reported to be 3.…

Uses

The primary industrial use of boric acid is in the manufacture of monofilament fiberglass usually referred to as textile fiberglass. Textile fiberglass is used to reinforce plastics in applications that range from boats, to industrial piping to computer circuit boards.
In the jewelry industry, boric acid is often used in combination with denatured alcohol to reduce surface oxidation and firescale from forming on metals during annealing and soldering operations.

Overview

  • Boric acid and its sodium borate salts are pesticides that we can find in nature and many products. Borax is one of the most common products. Boric acid and its sodium salts each combine boron with other elements in a different way. In general, their toxicities each depend on the amount of boron they contain.

Effects

  • Boric acid can kill insects if they eat it. It disrupts their stomach and can affect their nervous system. It can also scratch and damage the exterior of insects. Boric acid and borax, a sodium borate salt, can kill plants by causing them to dry out. Sodium metaborate, another sodium borate salt, stops plants from producing the energy they need from light. Boric acid can also stop the gr…
