What is meant by conjugate acid base pair? Find the conjugate acid l base for the following species: HNO_2,CH^(-),HClO_4,OH^(-),CO_3^(2-),S^(2-)

Answer»

Solution :An acid base pair which DIFFERS by a proton only `(Ha leftrightarrow A^(-)+H^+)` is known as CONJUGATE acid-base pair.
Conjugate acid : `HCN,N_2O,HCO_3^(-),HS^(-)`
Conjugate base `NO_2^(-),ClO_4^(-),O_2^(-)`
