Unformatted text preview: KSCN from 1 mL to 5 mL. Using values from the spectrophotometer and calibration curve, we could determine the equilibrium concentration of FeSCN by using an ICE table. The average K eq was 153.2481 for all the solutions. The standard deviation was 15.19053 for all the solutions. These results were what we expected to see as changing the concentration of SCN was not supposed to affect K eq under similar conditions. Solution #1 strayed from the values (causing the somewhat high standard deviation number) a little bit and that could be due to misuse of the spectrophotometer or not preparing the solution correctly. Either way, the experiment verified its objective, which was to show that K eq does not depend on the concentration of starting materials....
