Chapter 8, Problem 54E

Consider the following pH curves for $\text{100}\text{.0 mL}$ of two different acids with the same intital concentration each titrated by $0.10M\text{ NaOH:}$

1. Which plot represents a pH curve of a weak acid, and which plot is for a strong acid? How can you tell? Cite three differences between the plots that help you decide.

In both cases the pH is relatively constant before the pH changes greatly. Does this mean that at some point in each titration each solution was a buffered solution?

True or false? The equivalence point volume for each titration is the same. Explain your answer.

True or false? The pH at the equivalence point for each titration is the same. Explain your answer.
