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

Explanation

First part: N/A
Second part: Conjugate acids of `CN^(-),F^(-),OH^(-),CO_(3)^(2-) and S^(2-)` are HCN, HF, `H_(2)O,HCO_(3)^(-) and HS^(-)` respectively. Conjugate bases of `HNO_(3),HClO_(4) and OH^(-)` are `NO_(3)^(-),ClO_(4)^(-) and O^(2-)` respectively.
