Q. An aqueous solution of boric acid is found to be weakly acidic in nature. This acidic character arises due to the following reasons
The p-Block Elements
A
It is a protic acid which donates protons in aqueous solution
15%
B
It is a Lewis acid which abstracts $OH^{-}$ from water and leaves $H^{+}$ to make the solution acidic
55%
C
It gives metaboric acid when dissolved in water
20%
D
It is prepared by reaction of borax with sulphuric acid hence it behaves as an acid
10%
Solution:
It reacts with water to abstract $OH^{-}$ ions and releases $H_{3}O^{+}$ ions making it acidic.
$H_{3}BO_{3}+H_{2}O \to H_{3}O^{+}+H_{2}BO_{3}^{-}$
