A student performs an acid-base titration and plots the experimental results in the graph above. Which of the following statements best explains the experimental findings?

• A strong acid was titrated with a strong base, as evidenced by the equivalence point at pH = 7.

• A strong acid was titrated with a strong base, as evidenced by the equivalence point at pH > 7.

• A weak acid was titrated with a strong base, as evidenced by the equivalence point at pH > 7.

• A weak acid was titrated with a weak base, as evidenced by the equivalence point at pH approximately 7.
