Calculate the pH of a buffer solution containing 0.1 mole of acetic acid and 0.15 mole of sodium acetate. `K_(c)` for acetic acid is `1.75 xx 10^(-5)`.

Explanation

To calculate the pH of the buffer solution containing 0.1 mole of acetic acid and 0.15 mole of sodium acetate, we can use the Henderson-Hasselbalch equation:

### Step 1: Identify the components
We have:
- Acetic acid (weak acid) = 0.1 moles
- Sodium acetate (conjugate base) = 0.15 moles
- \( K_a \) for acetic acid = \( 1.75 \times 10^{-5} \)
