WebpH, pOH, and K a pH and pOH Adding an acid to water increases the H 3 O + ion concentration and decreases the OH - ion concentration. Adding a base does the opposite. Regardless of what is added to water, however, the product of the concentrations of these ions at equilibrium is always 1.0 x 10 -14 at 25 o C. [H 3 O + ] [OH -] = 1.0 x 10 -14 WebAcidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. know how to compare the H+ and OH- concentrations in solutions of different pH values - The acidity of the solution increases with the amount of [H+] ions present. The more [OH-] ions there are in the solution, the more basic it is.
