Answer
Yes, $HS{O_4}^-$ is amphiprotic, because it is capable of both receiving and donating one hydrogen ion ($H^+$).
Work Step by Step
- $HS{O_4}^-$ can receive one proton, producing $H_2SO_4$.
- $HS{O_4}^-$ can donate a proton, producing $S{O_4}^{2-}$.
A molecule or ion that can donate or receive one proton is called amphiprotic.
