Determine the degree if ionization and pH of `0.05 M` of ammonia solution. The ionization constant of ammonia can be taken from Table 7.7. Also calculate the ionization constant of the conjugate acid of ammonia.

Explanation

To solve the problem step by step, we will determine the degree of ionization (α) and pH of a 0.05 M ammonia solution. We will also calculate the ionization constant (Ka) of the conjugate acid of ammonia (NH4+).

### Step 1: Write the ionization equation for ammonia
Ammonia (NH3) ionizes in water as follows:
\[ \text{NH}_3 + \text{H}_2\text{O} \rightleftharpoons \text{NH}_4^+ + \text{OH}^- \]

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