Amphoteric species can behave like acids and base i.e. it can donate and accept H+ ion.

Q. Which of the following constitutes a set amphoteric species -

$H_{3} O^{+}, H_{2} P O_{4}^{-}, H C O_{3}^{-}$

$H_{2} O, H P O_{4}^{2 -}, H_{2} P O_{2}^{-}$

$H_{2} O, H_{2} P O_{4}^{-}, H P O_{4}^{2 -}$

$H C_{2} O_{4}^{-}, H_{2} P O_{4}^{-}, S O_{4}^{2 -}$

Amphoteric species can behave like acids and base i.e. it can donate and accept H⁺ ion.
