Procedure | Observations
1. Prepare 10 dilutions of [Fe(SCN)]2+ by setting up ten large, clean test tubes. 2. In the first tube pipette 10 mL of 50/50 Fe(III):SCN- and 10 mL 0f distilled H2O. 3. In the second tube place 9.0 mL of 50/50 solution and 11 mL of H2O. 4. Continue this procedure until the last tube contains 1.0 mL of 50/50 solution and 19 mL of distilled H2O. 5. Mix all the solutions with a stirring rod to ensure homogeneous solutions. | 1st tube is 10 mL of 50/50 and 10 mL distilled H2O. Decreasing 50/50 concentration from right to left and then from right to left in the back row- See Figure Solutions are orange colored Intensity of solution color decrease from 1 to 10.
