Both questions complete Answer needed

Titration of Strong Acid
Calculate the pH during the titration of 100.0 mL
of 0.200 M HCI with 0.400 M NaOH. First what is
the initial pH (before any NaOH is added)?
Answer:
0.0699

When a small amount of acid is added to a
non-buffered solution, there is a large change
in pH.
Calculate the pH when 21.7 mL of 0.0028 M HCI
is added to 100.0 mL of pure water. Comment
and hint in the general feedback.
Answer:
3.216
Note, less moles of acid are added in this
example than in the following buffered example.
Yet, you will see that the pH change in the
buffered solution is smaller. (Hint, remember to
use the total volume in your pH calculation.)

A friend asks the following: Consider a buffered solution made up of the weak acid HA and its salt NaA. If a strong base like NaOH is added, the HA reacts with the OH to form A. Thus the amount of acid (HA) is decreased, and the amount of base (A) is increased. Analogously, adding HCI to the buffered solution forms more of the acid (HA) by reacting with the base (A). Thus how can we claim that a buffered solution resists changes in the pH of the solution? How would you explain buffering to this friend?
