0.1 M HA is tritrated against 0.1 M NaOH . Find the pH the end point . Dissociation constant for the end acid HA is `5 xx 10^(-6)` and degree of hydrolysis , `h lt 1 `

Explanation

To find the pH at the endpoint of the titration of a weak acid (HA) with a strong base (NaOH), we can follow these steps:

### Step 1: Identify the given data
- Concentration of HA (weak acid) = 0.1 M
- Concentration of NaOH (strong base) = 0.1 M
- Dissociation constant (Ka) for HA = \(5 \times 10^{-6}\)

### Step 2: Calculate the pKa of the weak acid
