    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.
