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
