The conjugate acid of ammonia is the ammonium ion, NH_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 NH_3, and I gets NH_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_2SO_4 is HSO_4^-, bisulfate anion. What is the conjugate base of bisulfate ion?

Can you tell me the conjugate base of NH_3? This species does not exist in water, but it does exist in liquid ammonia.
