This preview shows page 15 - 17 out of 17 pages.

8.(3 pts) Based on the volume of NaOH added in Step 9 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.
9.(6 pts) At volumes belowthe volume determined in Step 9 of the Data Analysis, discussthe relative changes in pH following subsequent NaOH additions. What happened to thepH following subsequent additions of NaOH afterthe Step 9 volume was reached? Why?Include the titration curve and second derivative curve from the Part BData Analysis.

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.
