Question: 1. A buffer solution contains 0.375 M C 6 H 5 NH 3 Br and 0.452 M C 6 H 5 NH 2 ( aniline

1. A buffer solution contains 0.375 M C₆H₅NH₃Br and 0.452 M C₆H₅NH₂ (aniline). Determine the pH change when 0.130 mol HCl is added to 1.00 L of the buffer. pH after addition pH before addition = pH change =

2. Determine the pH change when 0.082 mol NaOH is added to 1.00 L of a buffer solution that is 0.332 M in HCN and 0.312 M in CN^-. pH after addition pH before addition = pH change =
