The acid dissociation constant of HPO42 2- 4²- is less than the acid dissociation constant of H₂PO4. This is because O it's harder to remove an H+ from H₂PO4 than from HPO4²- bases are always weaker than acids O it's harder to remove the H+ from HPO42- than from H₂PO4 - 2- OHPO4²- is part of a buffer system
