Boric acid is an acid because its molecule

contains replaceable $H^+$ ion

gives up a proton

accepts $OH^-$ from water releasing proton.

combines with proton from water molecule.

(NEET-2016)

Solution

Boric acid is an acid because its molecule accepts $\mathrm{OH}^{-}$ from water releasing proton

$\mathrm{B}(\mathrm{OH})_{3}+\mathrm{H}_{2} \mathrm{O} \longrightarrow\left[\mathrm{B}(\mathrm{OH})_{4}\right]^{(-)}(\mathrm{aq})+\mathrm{H}^{(-)}(\mathrm{aq})$
