Chemistry - Ionic Equilibrium Question with Solution | TestHub

Boric acid is not a protic acid. Boric acid is a weak monobasic acid. It is not a protonic acid but acts as a Lewis acid by accepting electrons from a hydroxyl ion and in turn releases ${\mathrm{H}}^{+}$ ions
Related Theory Although Boric acid contains $3\mathrm{OH}$ groups yet it can act as monobasic acid rather than tribasic acid, since, only one ${\mathrm{H}}^{+}$can be released by a water molecule.
