An acetic acid/acetate buffer was created by starting with a solution of acetic acid.
To make the buffer with the desired pH, sodium hydroxide was then added to
convert the acetic acid to its conjugate base.
Acetic acid has a pka of 4.8.
0.3 M NAOH stock solution was used to prepare 400 mL of acetic acid/acetate
buffer at pH 5.9 with a total concentration of 0.125 M. At this pH the concentration
of acetic acid was 0.014 M and the concentration of acetate was 0.111 M.
How many ml of NAOH stock solution have been added to establish the buffer?
Provide the answer to one decimal place. Do not include the unit ml in the answer
box.
