Tube A Tube A Tube A b. Looking at the standard curve only, describe what you see (describe what is good and/or bad) in a Sample 1 |Sample 1 |Sample 1 qualitative manner for the standard curve using the absorbance data and the information on the graph (you Tube B Tube B Tube B Sample 2 |Sample 2 |Sample 2 are making a qualitative assessment). Based on your qualitative assessment of the standard curve data, Tube C Tube C Tube C Sample 3 |Sample 3 Sample 3 would you use this curve to determine the concentrations of unknown samples?

Now make a qualitative assessment of the absorbance values for each of the samples (describe what is good and/or bad) and then calculate the concentration of each sample. For each sample comment on how Absorbance Values : confident you are that the calculated concentration of the sample is accurate.
