The conjugate base of ammonium ion, #NH_4^+#, is ammonia, #NH_3#.............

Explanation:

.........And the conjugate acid of bisphosphate ion, #HPO_4^(2-)#, is #H_2PO_4^-#.

As with all of these conjugate acid/conjugate base problems, I am simply simply exchanging a proton, #H^+#, and conserving mass AND charge. If mass and charge were not conserved, it would not be a realistic exercise.

What are the conjugate bases of #H_2SO_4#, #HSO_4^-#, #NH_3#, #HO^-#, and #NH_2^-#? What are their conjugate acids?
