How is the concentration of hydronium `(H_(3)O^(+))` ions affected when a solution of an acid is diluted?

Explanation

To understand how the concentration of hydronium ions (H₃O⁺) is affected when a solution of an acid is diluted, we can follow these steps:

### Step-by-Step Solution:

1. **Define Concentration**:
- Concentration is defined as the amount of a substance (in moles) divided by the volume of the solution (in liters). Mathematically, it can be expressed as:
\[
\text{Concentration (C)} = \frac{\text{Moles of solute}}{\text{Volume of solution (L)}}
