Calculate the hydrolysis constant. Degree of hydrolysis and pH of a 0.1 M `NH_4Cl` solution at ` 25 ^(@) C ` Given : `K_b " for " NH_4OH= 1.8 xx 10^(-5)`

Explanation

To solve the problem, we need to calculate the hydrolysis constant (K_h), the degree of hydrolysis (H), and the pH of a 0.1 M NH₄Cl solution at 25°C. Given that K_b for NH₄OH is 1.8 × 10^(-5), we can follow these steps:

### Step 1: Calculate the Hydrolysis Constant (K_h)

The hydrolysis constant (K_h) can be calculated using the formula:

\[
K_h = \frac{K_w}{K_b}
