**Title: Calculating the pH of an Aqueous Solution of Benzoic Acid**

**Instruction:**

Use the references to access important values if needed for this question.

**Problem Statement:**

Calculate the pH of a 0.528 M aqueous solution of benzoic acid (C₆H₅COOH). The acid dissociation constant (Kₐ) for benzoic acid is given as 6.3 x 10⁻⁵.

**Formula to Calculate pH:**

The formula to determine the pH of an acidic solution is:

\[ \text{pH} = -\log[\text{H}^+] \]

Where \([\text{H}^+]\) is the concentration of hydrogen ions in the solution.

**Task:**

Determine the concentration of hydrogen ions \([\text{H}^+]\) using the provided concentration of the acid and the acid dissociation constant, and then calculate the pH using the above formula.

**Additional Notes:**

- Use the quadratic formula if needed to solve for hydrogen ion concentration.
- For weak acids like benzoic acid, assume that \([\text{H}^+]\) is much smaller than the initial concentration of the acid. 

**Answer Box:**
