7. Compare and contrast a dilute solution of a strong acid
and a concentrated solution of a weak acid.
8. Describe two techniques used to measure the pH of a solution.
9. Explain how electricity can be conducted by acids and bases.
10. Relate pH values of 9.1, 1.2, and 5.7 to hydronium and hydroxyl ion
concentration and characterize each as basic, acidic, or very acidic.
11. the proper pH range for a swimming pool is
between 7.2 and 7.8. Most pools use two substances, Na, Co, and
HCI, to maintain this range. How would you adjust the pH if you
found it was 8.2? 6.9?
12. To determine the difference in pH strength, calcu-
late 10", where n is the difference between pHs. How much more
acidic is a solution of pH 2.4 than a solution of pH 4.4?
