Why Boric Acid Is A Weak Acid
Answers
Boric acid behaves as Lewis acid because it accepts a lone pair of electrons from OH− ions from water. Boric acid considered as weak acid because it does not dissociate to produce ions rather forms metaborate ion and in turn release ions.
Answer:
Boric acid is monobasic acid and weak Lewis acid.
Boric acid contains 3−OH groups yet it acts as monobasic acid rather than tribasic acid. Because boric acid does not act as proton donor but it accepts a lone pair of electrons from OH
−
ions and forms B(OH)
