(i) State the formula and name the conjugate base of each of the following species :
`(a) H_(3)O^(+) (b) HSO_(4)^(-) (C ) NH_(4)^(+) (d) HF (e ) CH_(3)COOH (f) CH_(3)NH_(3)^(+) (g) H_(3)PO_(4)(h)H_(2)PO_(4)^(-).`
(ii) State the formula and name the conjugate acid of each of the following species :
`(a) OH^(-) (b) HPO_(4)^(2-) (C) H_(2)PO_(4)^(-) (d) CH_(3)NH_(2) (e) CO_(3)^(2-) (f) NH_(3)(g) CH_(3)COO^(-) (h) HS^(-)`

Explanation

The conjugate base of an acid can be obtained by removing `H^(+)` ion. Therefore the conjugate bases of the species are :
