Determine the dergee of dissociation of `0.05 M NH_(3)` at `25^(@)C` in a solution of `pH = 11`

Explanation

To determine the degree of dissociation (α) of a 0.05 M solution of NH₃ at 25°C in a solution with a pH of 11, we can follow these steps:

### Step 1: Write the dissociation reaction of NH₃
The dissociation of ammonia (NH₃) in water can be represented as:
\[ \text{NH}_3 + \text{H}_2\text{O} \rightleftharpoons \text{NH}_4^+ + \text{OH}^- \]

### Step 2: Set up the initial and equilibrium concentrations
Let the initial concentration of NH₃ be \( C = 0.05 \, \text{M} \). At equilibrium, if α is the degree of dissociation, the concentrations will be:
