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 ammonium chloride is added, we can use the Henderson-Hasselbalch equation, as this scenario involves a buffer solution. Here’s a step-by-step solution:

### Step 1: Identify the components of the buffer solution
We have:
- Base: Ammonia (NH₃)
- Conjugate acid: Ammonium chloride (NH₄Cl)

Both are present at the same concentration of 0.033 M.
