About Boric Acid

As the name suggests, this compound is a weak acid of boron with the formula H3BO3. Also known as boracic acid or hydrogen borate, boric acid appears in the form of colourless crystals or a white powder that easily dissolves in water.

Boric acid has a wide range of uses across many different industries. It is used:

  • As an insecticide for the control of ants, cockroaches, termites, fleas, etc
  • In the manufacture of flame retardants 
  • In the manufacture of textile fibreglass used to reinforce plastics
  • With silicone oil to manufacture silly putty
  • As an antiseptic for minor burns
  • As a preservative for wood, timber and cattle hides
  • As a pH buffer in swimming pools
  • As a neutron poison in nuclear power plants

Natural Occurrence

In natural condition, boric acid is a component of a mineral called sassolite. This occurs near volcanoes in places like Tuscany, Italy, the Lipari Islands and Nevada.

It is also found mixed with other compounds in boracite, boronatrocaicite or colemanite. Boric acid can also be found as a predominant salt in salt water.

Preparation

Boric acid can be synthesised by two main processes:

  1. Via a reaction between sodium tetraborate decahydrate (Na2B4O7·10H2O, also known as borax) and hydrochloric acid (HCl):Na2B4O7·10H2O + 2 HCl → 4 H3BO3 + 2 NaCl + 5 H2O
  2. As a by-product of hydrolysis of diborane (B2H6) or boron trihalides (BX3, where X can be Bromium, Iodine or Chloride):B2H6 + 6 H2O → 6H2 + 2B(OH)3BX3 + 3 H2O → 3HX + B(OH)3
