PART ONE: Preparation of FECNS* Solution Prepare the two solutions in table 1 by accurately measuring the required volumes of distilled water and CNS into two labeled test tubes. The absorbance of the solutions must be measured soon after adding the Fe" solution from a buret. TABLE 1 Fe 5 ml 5S mL Solution Distilled Water CNS 2 mL Total Volume 3 ml 2 ml 10 ml 3 mL 10 ml In this part of the experiment you are to explore what the above quote means. As a PRELIMINARY Exercise, formulate a hypothesis as to what would happen under each of the following circumstances: 1. 1ml of 0.0020 M CNS' solution is added to the unused portion of solution 1 in the test tube 2. One drop of 0.20 M CNS solution is added to the unused portion of solution 2 in the test tube.

The spectrophotometer is set at 600 nm. The absorbance of each cuvette is read. The data is shown below: Cuvette 1 is the clank Cuvette # ml albumin Absorbance 0. 0.2 .063 3 0.4 .163 4. 0.6 .187 0.8 .253 1.0 .289 Using this data, plot an Excel graph showing absorbance (y-axis) vs ml albumin (x-axis). Find the correlation coefficient (r). R2 > 0.99 = excellent data; r2 0.98-0.95 good data r2 0.94 -0.90 = fair data. How would you describe this data?- To find the relative sensitivity, for each of tubes 2-6 (neglect blank), perform the following operation absorbance (Lowry)/Absorbance (Biuret x 0.5 gram albumin (Biuret)/0.05 gram (Lowry) x 200 ml (Lowry)/100 mL (Biuret). This implifies to Relative sensitivity = 20 dilution factor x absorbance (Lowry)/Absorbance (Biuret). Report your relative sensitivity as an average of all 5 values.
