What is meant by the conjugate acid-base pair ? Find the conjugate acid/base for the secies :
`HNO_(2), CN^(-), HClO_(4),F^(-),OH^(-),CO_(3)^(2-) and S^(2-)`

Answer 1

An acid-base pair which differ by a proton is called conjugate acid base pair .
`NO_(2)^(-), HCN, ClO_(4)^(-) , HF, H_(2)O ` (acid) or `O^(2-) ` (base), `HCO_(3)^(-) and HS^(-)`.
