Calculate the pH of each of the following solution
(i) 100 ml of 0.1 M `CH_(3)COOH` mixed with 100 ml of 0.1 M NaOH.
(ii) 100 ml of 0.1 M `CH_(3)COOH` mixed with 50 ml of 0.1 m NaOH
(iii) `50 ml of 0.1 M CH_(3)COOH` mixed with 100 ml of 0.1 M NaOH.
`K_(a)(CH_(3)COOH)=1.8xx10^(-5)`

Explanation

To calculate the pH of the given solutions, we will follow a systematic approach for each case.

### Given Data:
- **Acetic Acid (CH₃COOH)**: 0.1 M
- **Sodium Hydroxide (NaOH)**: 0.1 M
- **Volume of Acetic Acid (CH₃COOH)**: 100 ml for (i) and (ii), 50 ml for (iii)
- **Volume of Sodium Hydroxide (NaOH)**: 100 ml for (i), 50 ml for (ii), 100 ml for (iii)
- **Ka (Acetic Acid)**: 1.8 × 10⁻⁵
