Question

What is true about orthoboric acid in aqueous medium?

• A. Monobasic
• B. Dibasic
• C. Tribasic
• D. All are correct

Answer 1

Answer: (A)

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

$H_{3}B{O}_3$ is a weak monobasic acid it does not act as a $H^{+}$ donor but behaves as a Lewis acid.
