Explanation :
According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.
Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor
The given equilibrium reaction is,
[tex]CH_3COO^-+HCO_3^-\rightleftharpoons CH_3COOH+CO_3^{2-}[/tex]
In this reaction, [tex]CH_3COO^-[/tex] and [tex]HCO_3^-[/tex] are act as Bronsted Lowry base and acid respectively and [tex]CH_3COOH[/tex] and [tex]CO_3^{2-}[/tex] are act as Bronsted Lowry acid and base respectively.
The formula of conjugate of [tex]CH_3COO^-[/tex] is, [tex]CH_3COOH[/tex]
The formula of conjugate of [tex]HCO_3^-[/tex] is, [tex]CO_3^{2-}[/tex]
