**Task Overview: Buffer Solution Analysis**

**Scenario:**
Consider a buffer made by adding 132.8 g of NaC₇H₅O₂ to 300.0 mL of 1.31 M HC₇H₅O₂ (Ka = 6.3 x 10⁻⁵).

**Question:**
What is the pH of the buffer after 0.250 mol of OH⁻ have been added?

**Discussion:**
This exercise involves calculating the pH of a buffer solution after the addition of a strong base (OH⁻). The buffer consists of benzoic acid (HC₇H₅O₂) and its sodium salt (NaC₇H₅O₂), which act as a weak acid and its conjugate base.

To solve this problem, you should:
1. Determine the initial concentrations of the acid and its conjugate base.
2. Apply the Henderson-Hasselbalch equation to calculate the buffer's pH after adding the base.
