What will be the hydrogen ion concentration of a solution obtained by mixing 500 ml of `0.20 ` M acetic acid 500 ml of `0.30` M sodium acetate ` (K_(a) = 1.75 xx 10^(-5))`

Explanation

To find the hydrogen ion concentration of a solution obtained by mixing 500 ml of 0.20 M acetic acid and 500 ml of 0.30 M sodium acetate, we can follow these steps:

### Step 1: Identify the components
We have:
- Acetic acid (weak acid): \( \text{CH}_3\text{COOH} \) with a concentration of 0.20 M
- Sodium acetate (salt of the weak acid): \( \text{CH}_3\text{COONa} \) with a concentration of 0.30 M

### Step 2: Calculate the moles of acetic acid and sodium acetate
