Question
Basicity of $H_3BO_3$ is :
✓
Answer
Protic acid is an acid that can undergo ionization and produce hydrogen ions/protons. However, aprotic acids do not produce any hydrogen ions/protons.
Although Boric acid contains 3 OH groups yet it can act as monobasic acid rather than tribasic acid. This is because boric acid does not act as a proton donor rather it accepts a pair of
electrons from $\mathrm{OH}^{-}$ ions.
It does not donate $\mathrm{H}^{+}$ rather it accepts an electron pair from the solution or the donor i.e. $\mathrm{OH}^{-}$
Thus, Boric acid is an aprotic acid (like lewis acid) and monobasic acid.
