A 1L of buffer was prepared from 0.15 mole of Na2HPO4 and
0.10 moles KH2PO4. a) What is your pH and what is the pH change that adding
of 80.0 mL of 0.100 mol L-1 NaOH cause? b) What
happen to the pH after adding 10.0 mL of 1.0 mol L HNO3-1.

For a, use the Henderson-Hasselbalch equation.
For b, set up an ICE chart, substitute the new values into the HH equation.
Same for part c.
