Write the conjugate bases of the following acids and give reason: `HN_(3),CH_(3)OH,[Al(H_(2)O)_(6)]^(3+),NH_(4)^(+),HPO_(4)^(2-),H_(2)O_(2),OH^(-)`.

Explanation

According to Bronsted-Lowry concept, ann acid is a substance which can donate proton. The species formed when an acid donates a proton is called the conjugate base of the acid. The conjugate base of an acid has one fewer H-atom than the acid. Therefore, the conjugate
bases of `HN_(3), CH_(3)OH,[Al(H_(2)O)_(6) ]^(3+),NH_(4)^(+),HPO_(4)^(2-),H_(2)O_(2) and OH^(-)` are `N_(3)^(2-),CH_(3)O^(-),[Al(H_(2)O)_(5)OH]^(2+),NH_(3),PO_(4)^(3-) ,HO_(2)^(-) and O^(2-)` respectively.
