        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.

    ► 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.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.

     

     

     

     

     

     ►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 [or H3BO3] + 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

     

    BX3 + 3 H2O → B(OH)3 + 3 HX (X = Cl, Br, I)

     

     

     

     ►Application 

     

    1. Insecticidal

     

          Boric acid was first registered in the US as an insecticide in 1948 for control of

     

    cockroaches, termites, fire ants, fleas, silverfish, and many other insects. The

     

    product is generally considered to be safe to use in household kitchens to control

     

    cockroaches and ants.It acts as a stomach poison affecting the insects'

     

    metabolism, and the dry powder is abrasive to the insects' exoskeletons. Boric acid

     

    also has the reputation as "the gift that keeps on killing" in that roaches that cross

     

    over lightly dusted areas do not die immediately, but that the effect is like shards of

     

    glass cutting them apart. This often allows a roach to go back to the nest where it

     

    soon dies. Cockroaches, being cannibalistic, eat others killed by contact or

     

    consumption of boric acid, consuming the powder trapped in the dead roach and

     

    killing them, too.

     

     

     

    2. Preservation

       

         In combination with its use as an insecticide, boric acid also prevents and

     

    destroys existing wet and dry rot in timbers. It can be used in combination with an

     

    ethylene glycol carrier to treat external wood against fungal and insect attack. It is

     

    possible to buy borate-impregnated rods for insertion into wood via drill holes

     

    where dampness and moisture is known to collect and sit. It is available in a gel

     

    form and injectable paste form for treating rot affected wood without the need to

     

    replace the timber. Concentrates of borate-based treatments can be used to

     

    prevent slime, mycelium, and algae growth, even in marine environments.

     

    Boric acid is added to salt in the curing of cattle hides, calfskins, and sheepskins.

     

    This helps to control bacterial development, and helps to control insects.

     

     

    3. Agriculture

     

         Boric acid is used to treat or prevent boron deficiencies in plants. It is also used

     

    in preservation of grains such as rice and wheat.
