During this part #3 of the lab, you will make 2 acetic acid buffer solutions (HC2H3O2/NaC2H3O2) of the same pH (pH = 4.0), but with different concentration of the components. Use the Henderson -Hasselbalch equation to perform the following calculations. The Ka of acetic acid is 1.8 x 10-5 M.
a. Buffer A: Calculate the mass of the solid sodium acetate (NaC2H3O2) required to mix with 100 ml of 0.1 M acetic acid (HC2H3O2), to prepare a pH 4 buffer.
b. Buffer B: Calculate the mass of the solid sodium acetate (NaC2H3O2) required to mix with 100 ml of 1.0 M acetic acid (HC2H3O2), to prepare a pH 4 buffer.
