buffers consist of conjugate acid base pairs, which only differ by 1 H. These two differ by an H AND a K, so how come they are a conjugate acid base pair?

K2HPO4 is an amphoteric substance. It can act as an acid and also as a base. When an acid is added to K2HPO4, it acts as a base. H+ + HPO42- --> H2PO4- or HCl + K2HPO4 --> KCl + KH2PO4 When a base is added to K2HPO4, it acts as an acid. OH- + HPO42- --> PO43- + H2O or KOH + K2HPO4 --> K3PO4 + H2O Hope this helps!

A buffer in this case is the mixture of a weak base and its conjugate acid. The chemical equation would be PO4 -3 + H+ <---> HPO4 -2.
