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

Explanation

To determine 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. **Understanding Hydronium Ion Formation**:
- Hydronium ions (H₃O⁺) are formed when hydrogen ions (H⁺) from an acid react with water. H⁺ ions are not stable in solution and thus exist as H₃O⁺.

2. **Initial Concentration of Acid**:
...
