A buffer made by mixing equal amounts of acetic acid and sodium acetate.

1. Consider a buffer made by mixing equal amounts of acetic acid and sodium acetate.
Refer to equation 8-1 and
a. describe the relative amounts of each of the three components present in the buffer
solution,
b. predict what will happen to the concentrations of each of the three components if a
small amount of HCl is added, and
c. predict what will happen if a small amount of NaOH is added.
2. Generate an outline of a procedure for preparing 100 mL of an acetic acid/acetate buf-
fer.
3. If a buffer is prepared using equal amounts of acetic acid and sodium acetate, predict
what the pH of that solution will be.
4. If a buffer is made up to be 1.0 M in acetic acid and 1.0 M in sodium acetate, predict
how much acid will be required to change the pH of 100 mL of the buffer by 0.1 pH
units.

â–  PROCEDURES
Begin by calibrating your pH meter and electrode. 1. Prepare 100 mL of a solution that is 1.0 M in acetic acid and 1.0 M in sodium acetate.
Determine its pH.
2. Determine how much HO is required to change the pH by 0.1 pH units. 3. Determine how much NaOH is required to change the pH by 0.1 pH units.
