Question

$H_{3}B{O}_3$ is

• A. Monobasic and weak Lewis acid
• B. Monobasic and weak Bronsted acid
• C. Monobasic and strong Lewis acid
• D. Tribasic and weak Bronsted acid

Answer 1

Answer: (A)

Boric acid $\left(H_{3}B{O}_3\right)$ also called hydrogen borate. Boric acid and orthoboric acid is a weak, monobasic Lewis acid of boron.

However, some of its behaviour towards some chemical reactions suggest, it to be tribasic acid in the Bronsted sense as well.
