Question

In the reaction $ \mathrm{B}(\mathrm{OH})_{3}+2 \mathrm{H}_{2} \mathrm{O} \rightarrow\left[\mathrm{B}(\mathrm{OH})_{4}\right]^{-}+\mathrm{H}_{3} \mathrm{O}^{+} $ $ \mathrm{B}(\mathrm{OH})_{3} $ functions as, Bronsted acid, Lewis acid, Protonic acio, Lewis base

MARKS App · Accepted Answer

(B) Boric acid is a weak mono basic acid (not a protonic acid) but acts as a Lewis acid by accepting electrons from $ O H^{-} $ ions.
