Calculate the pH of `0.033` M ammonia solution if `0.033 M NH_(4)Cl` is introduced in this solution at the same temperature `(K_(b)` for `NH_(3)=1.77xx10^(-5)`)

Explanation

To calculate the pH of a 0.033 M ammonia solution when 0.033 M NH₄Cl is added, we can use the Henderson-Hasselbalch equation. Here are the steps to solve the problem:

### Step-by-step Solution:

1. **Identify Given Values:**
- Concentration of ammonia (NH₃) = 0.033 M
- Concentration of ammonium chloride (NH₄Cl) = 0.033 M
- Base dissociation constant (Kₐ) for NH₃ = 1.77 x 10^(-5)
