Vedclass · Accepted Answer

$HCO_3^{-}$

Vedclass · Answer

(B) Bronsted base is a substance that can accept a proton $(H^{+})$,while a Bronsted acid is a substance that can donate a proton $(H^{+})$.$HCO_3^{-}$ can accept a proton to form carbonic acid: $HCO_3^{-} + H^{+} \rightleftharpoons H_2CO_3$ (acting as a Bronsted base).$HCO_3^{-}$ can donate a proton to form carbonate ion: $HCO_3^{-} \rightleftharpoons H^{+} + CO_3^{2-}$ (acting as a Bronsted acid).Therefore,$HCO_3^{-}$ acts as both a Bronsted acid and a Bronsted base.

Which of the following can act both as a Bronsted acid and a Bronsted base?
