Question

On dilution of an aqueous solution of an acid, the
concentration of hydronium ion will​

Answer 1

Answer:

The concentration of hydronium ions decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ions decreases. When an acid is diluted, then the concentration of hydronium ions decreases.

Answer 2

Answer:

When the solution of an acid is diluted then its strength decreases as there is decrease in the concentration of hydronium (H3O+)ions. Diluting with water of an acid causes lowering of concentration of hydronium ion because of adding H2O but there are no excess H+ to make it (H3O+).

Explanation:

The concentration of hydronium ions decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ions decreases.
