Part 1: Describe the key characteristics of the graph. What do you notice? Does adding the acid (or base) change the pH in a regular, consistent way?

What was the approximate pH at the equivalence point (center of steep slope)?

Why is the pH not 7?

What is the approximate pH at the halfway point on the graph? (remember that is where OH- is half of the HA moles, and HA moles = A- moles). It is the "buffered" flatter region;)
