Question

A. Give the conjugate base of NH4+ ? B. Give the conjugate acid of 2 HPO4− ?

A. Give the conjugate base of NH4+ ?
B. Give the conjugate acid of 2 HPO4− ?

Answer 1

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?
