The species: `H_(2)O,HCO_(3)^(-),HSO_(4)^(-)` and `NH_(3)` can act both as Bronsted acids and bases. For each case give the corresponding conjugate acid and conjugate base.

Explanation

The answer is given in the following Table :
`{:("Species", "Conjugate acid", "Conjugate base"),(H_(2)O,H_(3)O^(+),OH^(-)),(HCO_(3)^(-),H_(2)CO_(3),CO_(3)^(2-)),(HSO_(4)^(-),H_(2)SO_(4),SO_(4)^(-2)),(NH_(3),NH_(4)^(+),NH_(2)^(-)):}`
