    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

► 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.









     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




B2H6 + 6 H2O → 2 B(OH)3 + 6 H2


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






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.
