Vedclass · Answer

(C) $Br\o nsted$ acid is a proton $(H^+)$ donor,and a $Br\o nsted$ base is a proton $(H^+)$ acceptor.Species that can both donate and accept a proton are called amphoteric.$NH_3$ can accept a proton to form $NH_4^+$ (acting as a base) but cannot donate a proton under normal conditions.$CN^-$ can accept a proton to form $HCN$ (acting as a base) but cannot donate a proton.$HSO_4^-$ can donate a proton to form $SO_4^{2-}$ (acting as an acid) and can accept a proton to form $H_2SO_4$ (acting as a base).Therefore,$HSO_4^-$ acts as both a $Br\o nsted$ acid and a $Br\o nsted$ base.

Which of the following compounds can act as both a $Br\o nsted$ acid and a $Br\o nsted$ base?
