Question
Explain why it is not possible to prepare a buffer with a pH of 6.50 by mixing $\mathrm{NH}_{3}$ and $\mathrm{NH}_{4} \mathrm{Cl}$.
Step 1
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is achieved by using a weak acid with Show more…

Explain why a buffer can be prepared from a mixture of $\mathrm{NH}_{4} \mathrm{Cl}$ and NaOH but not from $\mathrm{NH}_{3}$ and $\mathrm{NaOH}$
Describe how to prepare a buffer solution from $\mathrm{NH}_{3}$ and $\mathrm{NH}_{4} \mathrm{Cl}$ to have a $\mathrm{pH}$ of 9.5
Briefly describe how a buffer solution can control the $\mathrm{pH}$ of a solution when strong acid is added and when strong base is added. Use $\mathrm{NH}_{3} / \mathrm{NH}_{4} \mathrm{Cl}$ as an example of a buffer and $\mathrm{HCl}$ and $\mathrm{NaOH}$ as the strong acid and strong base.
