**Question:**

When plotting a graph that measures pH levels of a weak acid at increasing volume of sodium hydroxide, the pH at equilibrium should be at pH 7.

- ○ True
- ○ False

**Explanation:**

This question assesses understanding of acid-base titration curves. When a weak acid is titrated with a strong base like sodium hydroxide, the equivalence point (equilibrium) will have a pH greater than 7. This is because the salt formed (from the conjugate base of the weak acid) will hydrolyze in water, resulting in a basic solution. Therefore, the statement is false.
