Description

Includes

Materials for 15 groups: 500mL Iron(III) Nitrate, 0.20M solution; 100mL Potassium Thiocyanate, 0.002M solution (2); 100mL Nitric Acid, 0.5M solution UN2031; teacher's guide; and student copy masters

To determine the equilibrium constant for the formation of a colored species.

Set up a series of solutions with known concentrations of the FeSCN2+ ion and measure the absorbance of each solution spectrophotometrically. We will then construct a standard curve that can be used to determine the concentration of the unknown solutions of the next part.
