Calculate the `pH` of `0.001MHOCl` having `25%` dissocation .Also calculate dissocation constant of the acid ,Take `log2=0.3`

Explanation

To solve the problem step by step, we will calculate the pH of a 0.001 M solution of HOCl with 25% dissociation and then find the dissociation constant of the acid.

### Step 1: Determine the concentration of dissociated ions
Given:
- Initial concentration of HOCl, \( C = 0.001 \, \text{M} = 10^{-3} \, \text{M} \)
- Degree of dissociation, \( \alpha = 25\% = 0.25 \)

The concentration of dissociated ions (both \( \text{OH}^- \) and \( \text{Cl}^+ \)) can be calculated as:
