WebWhen [H+] and [OH–] are present in equal amounts, the solution gives a neutral pH. Here [H+][OH–] = [H+]2 or [H+] = 1 × 10-14M2 and [H+] = [OH–] = 10-7M Because the total concentration of H+and OH–is constant, an increase in one ion is compensated by a decrease in the concentration of other ion. This forms the basis for the pH scale.
