Is boric acid a protic acid? Explain.
(N/A) Boric acid is not a protic acid. It is a weak monobasic Lewis acid.
It does not donate a proton $(H^+)$ directly. Instead,it acts as a Lewis acid by accepting a lone pair of electrons from the hydroxyl $(OH^-)$ ion of a water molecule.
The reaction is:
$B(OH)_3 + 2H_2O \longrightarrow [B(OH)_4]^- + H_3O^+$
