Worksheet & Grading Rubric – Weak Acids and Buffers
PART C: Buffered Acetic Acid vs. HCl(5 pts) Table 3: Relevant volumes and pH readings during the HCltitration of the buffer.
10.(3 pts) During the addition of HCl in Part C, which buffer species reacted with the HCl?Provide the balanced formula unit equation for this reaction.
11.(3 pts) Based on the volume of HCl added in Step 14 of the Data Analysis, determine thebuffering 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 toinclude the correct units.
