► Description 

 

 

     Boric acid, also called hydrogen borate, boracic acid, orthoboric acid and

 

acidum boricum, is a weak, monobasic Lewis acid of boron, which 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 crystals or a

 

white powder that dissolves in water. When occurring as a mineral, it is called

 

sassolite.

 

    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.

 

Boric acid was first prepared by Wilhelm Homberg (1652–1715) from borax,

 

by the action of mineral acids, and was given the name sal sedativum

 

Hombergi ("sedative salt of Homberg"). However borates, including boric

 

acid, have been used since the time of the ancient Greeks for cleaning,

 

preserving food, and other activities.
