An aqueous solution of borax is basic. Sodium borate, sodium tetraborate, and disodium tetraborate are further names for borax. It is a white, powdered material. It contains boron, sodium, and oxygen in combination. Chemical formula: Na2 [B4 O5 (OH)4 ]·8H2O.

Borax ionises when it is dissolved in water, and the hydrolysis of the Borate ion produces OH and Boric acid. In this case, Boric acid is a weak acid, while Na-OH is a strong alkali. As a result, the nature of the borax aqueous solution is alkaline.

Uses of Borax:

Herbicide, laundry enhancer, household cleaning, fungicide, etc.


An amphoteric substance in chemistry is a molecule or ion that reacts as both an acid and a base. In general, metallic oxides are basic, whereas non-metallic oxides are acidic. While some metallic or semi-metallic oxides are amphoteric, some non-metallic oxides are neutral. Al2 O3 and Ga2 O3 are examples of amphoteric compounds.
