Question

Read the following and select one the correct answer.

Statement I: In water, orthoboric acid behaves as a weak monobasic acid

Statement II: In water, orthoboric acid acts as a proton donor

• A. Statement I and Statement II are both correct. Statement II correctly explains Statement I
• B. Statement I and Statement II are both correct. Statement II does not explain Statement I
• C. Statement II is correct and Statement I is wrong
• D. Statement I is correct and Statement II is wrong

Answer 1

The correct option is D

Statement I is correct and Statement II is wrong

$H_{3}B{O}_3+H_{2}O\rightleftharpoons \left[B\right(OH{)}_4{]}^{-}+H^{+}$

Clearly, $H_{3}B{O}_3$ is an acceptor of $O{H}^{-}$ than a proton donor. So Statement I is correct and Statement II is wrong.
