For the conjugate base, simply remove a proton from the parent molecule/species and CONSERVE mass and charge.

Explanation:

If I remove H+ from H2O, clearly I get the hydroxide ion, OH. Mass and charge have been conserved. If I remove a proton from sulfuric acid, I get bisulfate anion, HSO4; thus bisulfate is the conjugate base of sulfuric acid. What is the conjugate base of bisulfate ion? What is the conjugate base of OH?

The conjugate base of ammonia, NH3, does not exist in water, but it does exist in liquid ammonia. What is it?
