An aqueous solution of boric acid is found to be weakly acidic in nature. This acidic character arises due to the following reasons.
- 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 the 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.
Answer
(B) It is a Lewis acid which abstracts OH – from water and leaves H + to make the solution acidic.
