Is boric acid a protic acid? Explain.
(N/A) Boric acid ($H_3BO_3$ or $B(OH)_3$) is not a protic acid.
$A$ protic acid is defined as a substance that donates a proton $(H^+)$ in an aqueous solution.
Boric acid acts as a weak monobasic Lewis acid.
It accepts a lone pair of electrons from the $OH^-$ ion of water to form the $[B(OH)_4]^-$ complex,thereby releasing $H^+$ ions into the solution:
$B(OH)_3 + 2H_2O \longrightarrow [B(OH)_4]^- + H_3O^+$
