Determination of Kc Post lab part B.
9. Repeat steps 6-7 for all the test tube mixtures. 10, 11. Properly discard your âDiluted Fe.3" solution; you are done with it. Perform the calculations to determine the value of β: find [FeSCN Graph the values and find the slope of the graph using the Microsoft Excel gra software in the Science Learning Center and A 1. Using burets, add the appropriate amounts of 0.0025 M Fe(NO)s, 0.0025 M KSCN, and 0.1 M HNOs to three clean, numbered (4-6) test tubes as listed in Table 2 NOTE: BE SURE YOU ARE USING THE CORRECT SOLUTIONS. Do TH E "DILUTED Fe OR THE 1 M KSCN SOLUTIONS FROM PARTA! TABLE 2 mL of TEST TUBE mL of mL of 0.0025 M Fe(vo) 1.00 1.00 1.00 0.0025 M KSCN 0.1 M HNOs 1.00 1.50 2.00 5,00 4.50 4.00 2. Once all the contents of a test tube have been added, use the vortex mixer to mix thoroughly Pour the reaction mixture from test tube 4 into a clean, dry cuvett so that it is two-thirds 3. full. Place the cuvette into the spectrophotometer, and record the %T at 450 nm. Repeat steps 3-4 for all the test tube mixtures. Record %T for each. Properly discard your solutions as directed by your lab instructor. 6.
