![### Buffer Solution pH Calculation
**Problem:**
Calculate the pH of a buffer solution that is 0.116 M in C₅H₅N (pyridine) and 0.152 M in C₅H₅NHCl.
**Instructions:**
Use the References to access important values if needed for this question.
---
**Solution:**
1. Identify the weak base (pyridine) and its conjugate acid (C₅H₅NHCl).
2. Apply the Henderson-Hasselbalch equation:
\[
\text{pH} = \text{p}K_a + \log \left( \frac{[\text{Base}]}{[\text{Acid}]} \right)
\]
3. Insert the given concentrations and calculate the pH.
