2. The size of a molecule is a factor that can greatly affect solubility of ions. Which molecule is larger, acetone or water? How could this affect the solubility of Nat and CI" ions in each solvent? 3. It is very likely that the acetone partition still contained a fairly good amount of water (and that the water partition contained acetone). Only one of the three concentration units will be affected by the water in the acetone solution. Which one is affected? Explain why, and why the other two concentration units will be unaffected by the amount of water.

In Part 1 of the experiment, you will generate a calibration curve in order to determine el for this reaction. In order to ensure that the [Fe(SCN)2*] for these calibration solutions is accurately known, a large excess of SCN is used, so that the equilibrium for these solutions lies heavily to the products, and we can assume all of the Fe2* added becomes Fe(SCN)2*. In Part 2, you will observe solutions prepared with various initial reactant concentrations in order to determine Keg for the formation of iron(II) thiocyanate.
