Calculate the concentration of `H_3O^(+) ` in a mixture of 0.03 M acetic acid and 0.1 M sodium acetate. Ionisation constant for acetic acid is `1.8 xx 10^(-5)`

Explanation

To calculate the concentration of \( H_3O^+ \) ions in a mixture of 0.03 M acetic acid and 0.1 M sodium acetate, we can follow these steps:

### Step 1: Write the dissociation equation for acetic acid
Acetic acid (\( CH_3COOH \)) dissociates in water as follows:
\[ CH_3COOH \rightleftharpoons CH_3COO^- + H^+ \]
