• # question_answer 4) Why is boric acid considered as a weak acid?

Boric acid itself does not release hydrogen ions. When it reacts with water, it receives $O{{H}^{-}}$ ions from water molecules to complete its octet and releases ${{H}^{+}}$ ions. $\underset{Orthoboric\,acid}{\mathop{B{{(OH)}_{3}}}}\,+2{{H}_{2}}O\to {{[B{{(OH)}_{4}}]}^{-}}+{{H}_{3}}{{O}^{-}}$
