Question

Boric acid is an acid because its molecule:

• A. accepts $O{H}^{-}$ from water releasing proton
• B. combines with proton from water molecule
• C. contains replaceable $H^{+}$ ion
• D. gives up a proton

Answer 1

The correct option is A accepts $O{H}^{-}$ from water releasing proton

Boric acid is an acid because its molecule accepts $O{H}^{-}$ from water releasing proton.The reaction is as follows:

$B(OH{)}_3+H_{2}O\rightleftharpoons [B(OH{)}_4{]}^{-}+H^{+}$

Hence, option A is correct.
