Boric acid condenses to form tetraboric acid according to the equation:
4H3BO3 (s) → H2B4O7 (s) + 5H2O (g)
Lewis acid having the formula H3BO3, boric acid is a monobasic Lewis acid. It is an acid made up of four oxygen atoms, one phosphorus atom, and three hydrogen atoms.
Boric acid is sometimes referred to as orthoboric acid, boracic acid, hydrogen borate, and acidum boricum. It possesses antiviral, antifungal, and antiseptic qualities and is a weak acid.Boric acid does not have a distinctive smell and is soluble in water.
Tetraboric acid is a dibasic acid with the formula H2B4O7 that is formed when ordinary boric acid is heated. It is best known in the form of its salts (as borax).
Therefore, boric acid condenses to form tetraboric acid according to the equation:
4H3BO3 (s) → H2B4O7 (s) + 5H2O (g)
