Specific Requirements from module on canvas:Post-lab Report Experiment 2

2.1 Buffers

Prepare a brief report explaining the procedure for preparing and measuring the potential buffers. Include the data from Table 1 and explain which mixture gave you the best buffer. Additionally, calculate the theoretical starting pH of each potential buffers and compare them to the experimental values you measured. Report the theoretical and experimental values in a table along with the % error for each.

2.2 Amino Acid Titration

Plot two graphs (titration curves), one showing pH vs mL of HCL added and one showing pH vs mL of NaOH added. Determine and report the pKas for each graph. Indicate how close your pKa values are to the literature values for your amino acid.

Remember to label the graph axes and provide enough tick marks along each axis to be useful.

Hint: The pKas should be the pH value at the point where you added half as much acid or base as you have amino acid. This applies to any line shape – your graphs likely won’t look like the one I modeled in class! You will have 2 pKas because amino acids have two ionizable groups.

NOTE: Attached is the example report, which is a guideline for how the report is supposed to look, as well as the procedures and data collected.
