The species which act as both an acid and a base is called amphoteric, e.g., HSO 32- . underset textacid HSO 32- arrow H ++ SO 32- underset text base HSO 3-+ H + arrow H 2 SO 3

Q. Which of the following species is amphoteric in nature?

$H_{3} O^{+}$

$H S O_{3}^{-}$

$S O_{3}^{2 -}$

$S O_{4}^{2 -}$

The species which act as both an acid and a base is called amphoteric,
e.g., $H S O_{3}^{2 -} . acid H S O_{3}^{2 -} \to H^{+} + S O_{3}^{2 -} base H S O_{3}^{-} + H^{+} \to H_{2} S O_{3}$
