WebThe equilibrium for the reaction of iron (III), Fe3+, with thiocyanate, SCN–, to yield the colored product, iron (III) thiocyanate, FeSCN2+, will be studied and its equilibrium constant determined spectroscopically using a Vernier Ocean Optics Spectrometer. A Beer's law plot will be made for iron (III) thiocyanate. WebJun 19, 2009 · To avoid precipitation of iron (III) hydroxide, you will include excess nitric acid (HNO 3) in all solutions, to shift this equilibrium far to the left. Because neither hydrogen ions nor nitrate ions are components of the iron (III) thiocyanate equilibrium, nitric acid does not affect the equilibrium position of the reaction that produces FeSCN 2+.

Web3. Replace the reference cuvette with the cuvette containing the iron-thiocyanate solution. Determine the wavelength of maximum absorbance, λmax, and use this wavelength in subsequent absorbance measurements. If the peak has an absorbance that is greater than about 2, the peak may be somewhat flattened or “off-scale.” WebIn this analysis the iron present in an iron tablet (dietary supplement) or a sample of food is extracted to form a solution containing Fe3+ (ferric) ions.
