you prepare a solution of 3.1 x 10-8M KOH and calculate the pH in the typical way for a strong base: calculate pOH (7.51), then pH = 6.49. When you place a pH meter in the solution you find that the pH is actually 7.11. What was wrong with your calculation? (Brief conceptual explanation is fine here – no calculations needed.)
