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

11 0.96 𝑚𝑜𝑙 1.5 𝐿 = 0.64M -log[0.64] = 0.19 35 g HCl 1 mol HCl 36.5 g HCl

12 What is the pH of a solution that contains 1
What is the pH of a solution that contains 1.98 grams of nitric acid (HNO3) dissolved in 650 mL of water? Molar Mass = 63.0 g/mol

13 1.98 g HNO3 1 mol HNO3 63.0 g HNO3 = mol 𝑚𝑜𝑙 0.650𝐿 = M -log[0.0483] = 1.32
