**Buffer pH Calculation Example**

**Problem:**

For a buffer initially containing 0.6 mol of NH₃ and 0.3 mol of NH₄Cl in 1.0 L, what is the pH after 0.1 mol of H⁺ is added to the buffer?

**Diagram Explanation:**

The diagram shows a container with two substances:

- 0.6 mol NH₃
- 0.3 mol NH₄⁺

An arrow indicates the addition of 0.1 mol H⁺ to this mixture.

**Answer Options:**

- ○ 9.55
- ○ 9.15
- ○ 9.35
- ○ 9.43
- ○ 9.79

This exercise involves using the Henderson-Hasselbalch equation to determine how the pH changes upon the addition of H⁺ ions to the buffer solution.
