The pKa's for phosphoric acid represent the following ionizations:
H3PO4 2 H2PO4+ H+
pK = 2.14
H2PO42 HPO42 + H*
pK = 7.20
HPO4 22 PO4 3+ H*
pK = 12.30
If 0.100 mole of H3PO4 and 0.140 moles of KOH are mixed and dissolved in water to a
final volume of 1.00 L, what is the pH?
H=7.02
What are the equilibrium concentrations of PO43- and
H;PO4 in this solution (not “negligible" or 0 M)?
[PO4] =.
[H;PO4] = .
