Calculate the degree of dissociation (ionization) of `0.05` M acetic acid if its `pK_(a) " is " 4.74`.

Explanation

To calculate the degree of dissociation (ionization) of 0.05 M acetic acid given its pKa value of 4.74, we can follow these steps:

### Step 1: Understand the dissociation of acetic acid
Acetic acid (CH₃COOH) dissociates in water as follows:
\[ \text{CH}_3\text{COOH} \rightleftharpoons \text{CH}_3\text{COO}^- + \text{H}^+ \]

### Step 2: Define the initial concentration
Let the initial concentration of acetic acid be \( C = 0.05 \) M. Initially, the concentrations of the ions (CH₃COO⁻ and H⁺) are 0.
