Buffer problem or not?

    Buffer problem or not??

    I have this problem and I worked it out completely, got my answers, and breathed a sigh of relief. Then, when I was looking through my notes and the book I noticed that the problem may have to be done completely differently because it might be a buffer problem. Can someone please tell me if it is a buffer problem?

    A weak acid HA (pKa=5.00) was titrated with 1.00M KOH. The acid solution had a volume of 100 mL and a molarity 0.100M. Find the pH at the following volumes of base added and make a graph of pH versus Vb: 0, 1, 5, 9, 9.9, 10, 10.1, and 12 mL.

    I did the whole problem assuming it was a simple pH problem. Do I need to treat it as a buffer since it is a titration of a weak acid with a strong base?
