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

$\bf\huge\underline\green{Answer}$

acid dissociates into hydronium ions (H3O+) and anions when dissolved in water. When a solution is diluted, the volume of the solution increases but the number of ions remains the same, so concentration of hydronium ions (H3O+) per unit volume decreases.
