As H3O+] increases, pH decreases, so acidic solutions have a pH of less than seven. Basic solutions have a pH greater than seven. The hydroxide and hydronium ion concentrations are related by the ion- product constant of water, K, as follows: Rank the solutions from the highest to lowest pH. To rank items as equivalent, overlap them. • View Available Hint(s) Reset Help K, = 1.0 x 10-14 = H3O+][OH| In the same way as the pH we can define the pOH as pOH = -log[OH ].
