Buffer Solution

Concept #1: Buffer Solution

Practice: A. What volume of 0.1 M acetic acid (pK a = 4.8) is required to make 1 liter of 0.1 M buffer solution at pH = 5.8?

B. What volume of 0.1 M sodium acetate is required to make the same buffer solution?

a. 193 mL                                                       

b. 91 mL 

c. 909 mL 

d. 807 mL

Concept #2: Buffer Solution

Practice: Which of the following compounds would make for the best buffer at pH 8?

Concept #3: Buffer Solution

Practice: MOPS (pKa =7.2) is a weak acid & acts as a buffer. Calculate the ratio of its basic/acidic species at pH = 6.0.
