An acid-base buffer is able to resist changes in pH due to the addition of small amounts of strong acid or base to the system. An acid-base buffer typically contains a weak acid and its conjugate base. 1st attempt Part 1 (1 point) Feedback It See Periodic Table See Hint A buffer is prepared by mixing 36.2 mL of 0.183 MNaOH with 108.4 ml of 0.172 Macetic acid. What is the pH of this buffer? (The pk for acetic acid is 4.75.) 40115 Feedback Part 2 (1 point) See Hint Calculate the pH of this buffer after the addition of 0.219 g of solid NaOH. * *712
Part 2 (1 point) Feedback See Hint When ammonia is then added, the precipitate dissolves and the solution turns a deep navy blue. What is the net chemical equation that describes this event? * X He- 8 Cu(OH),6) + 4NH3(aq) [Cu(NH3)4] + (aq) +2016)
