Problem- 1) A buffer solution contains 0.353 M NaH2PO4 and 0.218 M Na2HPO4. Determine the pH change when 0.055 mol HI is added to 1.00 L of the buffer.
pH after addition ? pH before addition = pH change =
2) Determine the pH change when 0.098 mol KOH is added to 1.00 L of a buffer solution that is 0.388 M in HF and 0.237 M in F-. pH after addition ? pH before addition = pH change =
