Title: Understanding pH Levels in Acid-Base Titrations

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

- ○ True
- ○ False

**Explanation:**
In a titration of a weak acid with a strong base like sodium hydroxide, the equivalence point typically occurs at a pH greater than 7. This is because the conjugate base formed in the reaction tends to slightly increase the pH beyond neutral.

Expert Solution
Step 1: Given data

Given:

A graph that measures pH levels of a weak acid at increasing volume of sodium hydroxide. 

Determine the pH at equilibrium when plotting this graph.

The pH of a solution is determined using the negative logarithm of the hydrogen ion concentration. The pH of a solution is a measure of its acidity or alkalinity on a logarithmic scale ranging from 0 to 14.

The equivalence point in a chemical titration is the point at which the stoichiometrically equivalent amounts of two reacting substances are combined.
