Preparing a strong base solution with a given pH A chemist must prepare 700.0 mL of potassium hydroxide solution with a pH of 12.00 at 25 °C. She will do this in three steps: ⚫ Fill a 700.0 mL volumetric flask about halfway with distilled water. • Weigh out a small amount of solid potassium hydroxide and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the mass of potassium hydroxide that the chemist must weigh out in the second step. Round your answer to 2 significant digits. g ☐ x10 ☑

Consider two solutions; one of a weak acid and one of a strong acid. How is it possible that a solution of weak acid can have a lower pH than a solution of strong acid? Select one: The concentration of the strong acid is higher than the concentration of the weak acid. The concentration of the weak acid is greater than the concentration of the strong acid. The weak acid only partially dissociates in solution. The strong acid completely dissociates in solution.
