1. pH/pOH Drill

2. Determine the pH of a 0.0096 M HNO3 solution

3. pH = -log[0.0096] = 2.0

4. Determine the pOH of a 0.0034 M HNO3 solution.

5. pH = -log[0.0034] pOH = = 11.5  12

6. Determine the pH of a 0.056 M KOH solution.

7. pOH = -log[0.056] = 1.3 pH = = 12.7  13

8. What is the pH if the pOH is 6?

9. pH = 14-6 = 8

10. What is the pH of a solution that contains 35 grams of hydrochloric acid (HCl) dissolved in 1.5 liters of water? Molar mass = 36.5 g/mol
