1.) Which solutions should you have used to make your Beer's Law Plot? 2.) What property of the product of your reaction allowed you to use visible spectroscopy to analyze your results? 3.) Using your absorbance value from Equilibrium mixture 5 (E5), show your calculation for the concentration of FeSCN^2+ in sample E5. (Provided picture for the resources)
Part 2: Preparation of equilibrium mixtures
1. Record the exact concentration of the 2.0x10-3M Fe(NO3)3 solution on your data sheet.
2. Label six test tubes "E1" through "E6" and place in test tube rack. You can use a paper
labeled E1-E6 under the test tube rack if necessary.
3. Transfer exactly 40 drops of 2.0x10-3M Fe(NO3)3 into the test tube labeled E1-E6.
4. Transfer the exact amount of 2.0 x 10-3 M solution NaSCN solution listed table below into
each of the corresponding test tubes.
5.0 drops
10.0 drops
15.0 drops
20.0 drops
