What is meant by the conjugate acid-base pair? Find the conjugate acid`//`base for the following species:
`HNO_(2), CN^(Θ), HClO_(4), F^(Θ), overset(Θ)(O)H, CO_(3)^(2-)`, and `S^(2-)`

Explanation

Conjugate acid base: The paris of acids bases which are formed form each other by the gain for loss of proton are called conjugate acid base Pairs.
`{:("Species",,"Conjugate acid"//"base"),(HNO_(2),,NO_(2)^(Θ)),(CN^(Θ),,HCN),(HCIO_(4),,ClO_(4)^(Θ)),(F^(Θ),,HF),(OH^(Θ),,H_(2)O),(CO_(3)^(2-),,HCO_(3)^(Θ)),(S^(2-),,HS^(Θ)):}`
