  1. The Determination of Keq for [FeSCN2+]

  2. Data Table 1: Find [FeSCN2+] • Find moles of your limiting reagent for each reference solution used: (KSCN): • X moles? 0.00020 M (KSCN) [FeSCN2+]

  3. Making a calibration Curve:

  4. Data Table 2- Test Solutions: Example for Test Solution #6: Concentration of Fe3+ ions = (0.0020M)(5.0mL)=( x M)(10.0mL) 1.0 x 10-3 M Concentration of SCN- ions = (0.0020M)(1.0mL)=( x M)(10.0mL) 2.0 x 10-4 M

  5. Data Table 3- Results: From Calibration Curve (look at absorbance and get concentration) [Fe3+] eq = [Fe3+]initial – [FeSCN2+]eq [SCN-] eq = [SCN-]initial – [FeSCN 2+]eq
