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. To make the presence of these ions in solution visible, thiocyanate ions (SCN−) are added. These react with the Fe3+ ions to form a blood-red coloured complex: Fe3+ (aq) + SCN− (aq) → ... 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.
