A liter of pH 7.20 phosphate buffer is needed for a certain experiment. The Henderson-Hasselbach equation will be sufficiently accurate for your determination of pH. The pK’s for possibly relevant phosphate species are: H3PO4 ↔ H2PO4- + H+ pK = 2.15 H2PO4- ↔ HPO4-2 + H+ pK = 7.20 HPO4-2 ↔ PO4-3 + H+ pK = 12.4 0.100 Moles of H3PO4 were dissolved in about 800 mL of water, and the pH was adjusted to 7.20 using a standardized pH...

Show calculation for the assigned buffer. Recall: [acid] + [base] = 0.20 M. Calculate the individual concentrations needed (mass or volume) for HA and A- based on your assigned buffer and pH. The condition [acid] + [base] = 0.20 M must be satisfied. The final volume of solution is 100.0 mL.
