The conjugate acid of ammonia is the ammonium ion, $N {H}_{4}^{+}$.

#### Explanation:

The conjugate acid of any species, is the original species PLUS a proton, ${H}^{+}$. Both mass and charge are conserved. So add a ${H}^{+}$ unit to $N {H}_{3}$, and I gets $N {H}_{4}^{+}$, ammonium ion. Are both mass and charge conserved here?

By the same procedure, if I remove ${H}^{+}$ from any species, I get the conjugate base. So the conjugate base of sulfuric acid, ${H}_{2} S {O}_{4}$ is $H S {O}_{4}^{-}$, bisulfate anion. What is the conjugate base of bisulfate ion?

Can you tell me the conjugate base of $N {H}_{3}$? This species does not exist in water, but it does exist in liquid ammonia.
