During the addition of NaOH in
, which buffer species reacted with the
NaOH? Provide the balanced formula unit equation for this reaction.
PART B: Buffered Acetic Acid vs. NaOH
: Relevant volumes and pH readings during the NaOH
titration of the buffer.
Based on the volume of NaOH added in Step 9 of the Data Analysis, determine the
buffering capacity of the buffered acetic acid solution. You may disregard the volume of
“1 L” from the definition and refer to the volume used of the original buffer. Be sure to
include the correct units.
