Boric Acid is a monobasic Lewis acid with the chemical formula H₃BO₃. It is an acid-containing compounds of boron, oxygen, and hydrogen. Boric acid is also known as acidum boricum, hydrogen borate, boracic acid, and orthoboric acid. It is a weak acid and has antiviral, antifungal, and antiseptic properties

Properties of Boric Acid

          Boric Acid appears as a colorless or white crystal under room temperature. The compound is highly soluble in water and has a molecular mass of 61.83 g/mol along with a pKa value between 8.92 and 9.24. It is known as sassolite in mineral form. Being a Lewis acid, the compound can accept electron pairs from a donor compound. Boric acid occurs in a planar configuration, where atoms attach themselves to the radical center, with all components positioned on the same plane

Use of Boric Acid 

      This Annex describes the use of borates in adhesives, (corrugated) paper and paperboard
products and in veneer sheets and pressed panels. In these uses, borates serve as multifunctional
additives with binder/adhesive, flame retardant and fungicidal properties. Due
to the multi-functional role of the borates in these products and applications, they have
been discussed collectively in this Annex.
