As [H3O+] increases, pH decreases, so acidic solutions have a pH of less than 7. Basic solutions have a pH greater than 7. The hydroxide and hydronium ion concentrations are related by the the ion-product constant of water, K, as follows: K=1.0 × 10-¹4 = [H3O+][OH-] In the same way as the pH, we can define the pOH as pOH = -log[OH-]. It follows from the K, expression that pH + pOH = 14. Part B Calculate the pH of a 0.10 M solution of barium hydroxide, Ba(OH)2.
