What will be the `pH` at the equivalence point during the titration of a `100 mL 0.2 M` solution of `CH_(3)CCOONa` with `0.2 M` solution of `HCl`? `K_(a)=2xx10^(-5)`

Options

A. `3-logsqrt(2)`
B. `3+logsqrt(2)`
C. `3-log2`
D. `3+log2`

Explanation

To find the pH at the equivalence point during the titration of a 100 mL 0.2 M solution of CH₃COONa with 0.2 M solution of HCl, we can follow these steps:

### Step 1: Calculate the number of millimoles of CH₃COONa and HCl
- **Given:**
- Volume of CH₃COONa = 100 mL
- Concentration of CH₃COONa = 0.2 M
- Volume of HCl = 100 mL
- Concentration of HCl = 0.2 M
