Purpose
The purpose of this experiment is to prepare 10 dilutions of [Fe(SCN)]2+
by settiranging from 0.0025M to 0.00025M.
* Note that when you make a mistake do not erase or cross out completely. Just put one line through it. Some of the more interesting discoveries in science have arisen from mistakes!

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.
