    ► 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.
