What is the effect of dilution on an acid or base?
Dilution is the process of decreasing the strength of an acid or base. We know that acids and bases produce H3O+ and OH- ions in water. When they are diluted (by having more amount of water), the concentration of H3O+ or OH- ions per unit volume decreases. This results in decrease of the strength of the acid or base.
