Question

18(a) Boric acid is a tribasic acid.

• A. True
• B. False

Answer 1

The correct option is B False

• Boric acid is a kind of monobasic acid and a weak Lewis acid.
• Lewis acid is a chemical species which is capable of accepting a lone pair of electrons from lewis base.
• Boric acid has three hydroxyl groups, although it is classified as a monobasic acid rather than a tribasic acid.
• Because boric acid does not act as proton donor but it accepts a lone pair of electrons from OH⁻ ions and forms B(OH)^4-.

Hence, the given statement is false.
