Calculate pH of `0.05` M Acetic acid solution , if `K_(a)(CH_(3)COOH) = 1.74 xx 10^(-5)`.

Explanation

To calculate the pH of a 0.05 M acetic acid solution given that the dissociation constant \( K_a \) for acetic acid is \( 1.74 \times 10^{-5} \), we can follow these steps:

### Step 1: Write the dissociation equation
The dissociation of acetic acid (\( CH_3COOH \)) in water can be represented as:
\[ CH_3COOH \rightleftharpoons CH_3COO^- + H^+ \]
