The conjugate acid of $N {H}_{3}$ is $N {H}_{4}^{+}$, ammonium ion; the conjugate base is $N {H}_{2}^{-}$, amide ion.

#### Explanation:

The amide ion does not exist in aqueous solution. Nor does the imide ion, $N {H}^{2 -}$, nor does azide ion, ${N}^{3 -}$ (which are the conjugate bases of which species?). In pure liquid ammonia these species might well exist.
