Vedclass · Answer

(C) An amphoteric species is one that can act as both a Bronsted-Lowry acid (donate a proton) and a Bronsted-Lowry base (accept a proton).$(I) \, H_2O$: Can accept a proton to form $H_3O^+$ and donate a proton to form $OH^-$. Thus,it is amphoteric.$(II) \, NH_2^-$: Can only accept a proton to form $NH_3$. It cannot donate a proton. Thus,it is not amphoteric.$(III) \, H_2PO_4^-$: Can accept a proton to form $H_3PO_4$ and donate a proton to form $HPO_4^{2-}$. Thus,it is amphoteric.$(IV) \, HCO_3^-$: Can accept a proton to form $H_2CO_3$ and donate a proton to form $CO_3^{2-}$. Thus,it is amphoteric.Therefore,$(I), \, (III),$ and $(IV)$ are amphoteric species.

Identify the amphoteric species among the following:
$(I) \, H_2O$
$(II) \, NH_2^-$
$(III) \, H_2PO_4^-$
$(IV) \, HCO_3^-$
