The pH of the resulting solution is 9.02.
Explanation:
The initial pH of the buffer solution can be found using the Henderson-Hasselbalch equation:
Now, the perchloric acid added will react with ammonia:
Also, the moles of ammonium chloride will increase in the same quantity according to the following reaction:
NH₃ + H₃O⁺ ⇄ NH₄⁺ + H₂O
Finally, we can calculate the pH of the resulting solution:
Therefore, the pH of the resulting solution is 9.02.
