#### Question

How is the concentration of hydronium ions (H3O+) affected when a solution of an acid is diluted?

#### Solution

When an acid is diluted, the concentration of hydronium ions (H3O+) per unit volume decreases. This means that the strength of the acid decreases.

Concentration of hydronium ions="Volume of solute (acid)"/"Volume of solution"

Is there an error in this question or solution?
