Boric acid has a single boron; its salt forms complex equilibria in solution, with the ion B4O7-2 being the predominant species.
Boric acid is used for weatherproofing wood and fireproofing fabrics; as a preservative; manufacturing of cements, crockery, porcelain, enamels, glass, borates, leather, carpets, hats, soaps, artificial gems; in nickeling baths; cosmetics; printing and dyeing, painting; photography; for impregnating wicks; electric condensers; hardening steel. It is also used as an insecticide for cockroaches and black carpet beetles. It is used in research labs as an astringent, antiseptic, antibacterial and antifungal agent. It is used in buffers and for calibration of polyacrylamide gel columns for the separation of oligonucleotides by capillary electrophoresis.
