Find the change in pH:
Part 1.
A buffer solution contains 0.318 M NaH2PO4 and 0.241 M Na2HPO4. Determine the pH change when 0.080 mol NaOH is added to 1.00 L of the buffer.
pH after addition - pH before addition = pH change = ________
Part 2.
A buffer solution contains 0.375 M C6H5NH3Br and 0.372 M C6H5NH2 (aniline). Determine the pH change when 0.090 mol NaOH is added to 1.00 L of the buffer.
pH after addition - pH before addition = pH change = _______
