An aqueous solution of boric acid is found to be weakly acidic in nature. This acidic character arises due to the following reasons.

Answer»

It is a protic acid which donates protons in aqueous solution.
It is a LEWIS acid which abstracts `OH^(-)` from water and leaves `H^(+)` to make to solution acidic
It gives metaboric acid when dissolved in water.
It is prepared by reaction of borax with sulphuric acid hence it behaves as an acid.

Solution :It REACTS with water to abstract `OH^(-)` ions and RELEASES `H_(3)O^(+)` ION making it acidic.
