What is Boric Acid?
Boric acid, also called hydrogen borate, boracic acid, and orthoboric acid, is a weak, monobasic Lewis acid of boron. However, some of its behavior towards certain chemical reactions is similar to that of the tribasic acid species. Boric acid is often used as an antiseptic, pesticide, flame retardant, neutron absorber, or precursor to other chemical compounds. It has the chemical formula H3BO3 and exists as colorless crystals or a white powder that dissolves in water. When it occurs as a mineral, it is called sasolite.
Boric acid is mainly found in free form in some volcanic regions, for example, in Tuscany, Italy, on the Lipari Islands, and in the US state of Nevada. It arises in volcanic environments mixed with steam from cracks in the ground. It is also found as a component of many naturally occurring minerals – borax, boracid, ulexite, and colemanite. Boric acid and its salts are found in sea water. It is also found in plants, including almost all fruits.
Boric acid was first prepared by Wilhelm Homberg by the action of mineral acids from borax, and the prepared product was called Homberg's soothing salt. However, borates, including boric acid, have been used for cleaning, food storage and other activities since the ancient Greeks.
How is Boric Acid produced?
Boric acid can be prepared by reacting borax (sodium tetraborate decahydrate) with a mineral acid such as hydrochloric acid:
na2B4HE710H2O + 2 HCl → 4 B(OH)3 [or H3BO3] + 2 NaCl + 5 H2HE
It also occurs as a byproduct of the hydrolysis of boron trihalides and diborane:
B2H6 + 6H2O → 2B(OH)3 + 6H2
BX3 + 3H2O → B(OH)3 + 3 HX (X = Cl, Br, I)

What are the uses (processes) of Boric Acid?
- The primary industrial use of boric acid is in the manufacture of monofilament/textile fiberglass. Textile fiberglass is used to reinforce plastic in a variety of applications, from boats to industrial piping to computer circuit boards.
- In the jewelry industry, boric acid is often used in combination with denatured alcohol to reduce surface oxidation and the formation of fire scales on metals during annealing and brazing operations.
- Boric acid is used in the production of glass in LCD flat panel displays.
- Boric acid is used in electroplating as part of some proprietary formulas.
- It is used as a fire retardant for wood.
- It is also used in the manufacture of ramming mass, which is a fine silica-containing powder used to manufacture induction furnace surfaces and ceramics.
- Boric acid is added to borax for use by blacksmiths as a welding flux.
- Boric acid in combination with polyvinyl alcohol (PVA) or silicone oil is used to produce Silly Putty.
- Boric acid can be used as an antiseptic for minor burns or cuts and is sometimes used in ointments and dressings, such as boric mohair.
- Dilute boric acid can be used as a vaginal douche to treat bacterial vaginosis due to excessive alkalinity and candidiasis due to non-albicans candida.
- As an antibacterial compound, boric acid can also be used as an acne treatment.
- It is also used to prevent athlete's foot by applying powder to socks or socks.
- Various preparations can be used to treat certain types of otitis externa (ear infection) in both humans and animals.
- Boric acid solutions used as eyewash or on abraded skin are known to be particularly toxic to infants, especially after repeated use; this is due to its slow elimination rate.
- Along with its use as an insecticide, boric acid also prevents and destroys wet and dry rot in woods.
- Concentrates of borate-based treatments can be used to inhibit the growth of slime, mycelium and algae even in marine environments.
- Boric acid is added to salt to improve cattle hides, calf skins and sheepskins. This helps control bacterial growth and control insects.
- Boric acid, the borate ion in equilibrium with its conjugate base, is widely used as a primary or auxiliary pH buffer system in swimming pools (concentration range 50 – 100 ppm boron equivalent).
- Boric acid is used to treat or prevent boron deficiencies in plants. It is also used in the preservation of grains such as rice and wheat.
- Boron is used in pyrotechnics to prevent amide-forming reaction between aluminum and nitrates.
- Boric acid can be used as a colorant to make fire green.
- Boric acid is used as a neutron poison in some nuclear power plants. The boron present in boric acid absorbs some thermal neutrons, reducing the possibility of thermal fission.
- Boric acid can be used as a lubricant on ceramic and metal surfaces.
