The pKa values of HPO4 (hydrogen phosphate) are as follows: pKa1 = 2.15, pKa2 = 7.20, and pKa3 = 12.35.
The conjugate base for HPO4^2- is H2PO4^-.
That's not a stable compound. If you meant HPO4--, it can be formed by either the reduction of the PO43- ion or oxidation of the H2PO4- ion.
The pKa of diisopropylamine is around 10-11.
The conjugate base of HPO4 2- is H2PO4 -, which results from the loss of one hydrogen ion (H+) from the dihydrogen phosphate ion.
The pKa values of phosphoric acid are 2.15, 7.20, and 12.35. These values correspond to the three dissociation steps of phosphoric acid, where each hydrogen ion is progressively released to form H2PO4-, HPO4^2-, and PO4^3- ions.
The conjugate base for HPO4^2- is H2PO4^-.
The conjugate base of HPO4^-2 is PO4^-3 because when HPO4^-2 loses a single hydrogen ion in a reaction, it forms PO4^-3.
HPO4²⁻ (hydrogen phosphate) and PO4³⁻ (phosphate) are both forms of phosphate ions. The relationship between them can be described by the equilibrium involving the dissociation of phosphoric acid (H₃PO₄). The relevant equilibrium reactions are: H₂PO4⁻ ⇌ H⁺ + HPO4²⁻ HPO4²⁻ ⇌ H⁺ + PO4³⁻ These reactions show how HPO4²⁻ can lose a hydrogen ion to form PO4³⁻.

The pKa of bromoacetic acid is approximately 2.64.
HPO4^2- is an acidic species as it can donate a proton (H+) in solution. NO2, on the other hand, can act as a base by accepting a proton. When mixed together, they can form a reaction where HPO4^2- donates a proton to NO2, leading to the formation of H2PO4^- and NO2^-.
The pH level of HPO4 (dihydrogen phosphate) depends on its concentration in solution. In general, HPO4 tends to be weakly acidic, causing the solution to have a pH below 7. At low concentrations, the pH may be closer to neutral, while at higher concentrations, it will be more acidic.

The pKa value of Doxofylline is approximately 4.22.
