Question

If true enter 1, if false enter 0.
$H_{3}B{O}_3$ is monobasic acid.

• A. 1

Answer 1

The correct option is A 1

Boric acid can be written as $B(OH{)}_3$ . The central boron in boric acid is electron deficient. When its added to water, boron accepts an electron pair from water as a lewis acid and water behaves as the corresponding lewis base.

$(OH{)}_{3}B\leftarrow O{H}_2$

So, now as oxygen on donation becomes positive, it releases an $H^{+}$ to form $\left[B\right(OH{)}_4{]}^{-}$ ion. As there is one $H^{+}$ released from the reaction of acid, it is called monobasic acid.
