Background Thiocyanate (SCN-) is natural occurring in the human body that is secreted in the salivary glands. To use Iron (III) thiocyanate as fake blood, it needs to be fairly dark, with an equilibrium concentration of 0.010 M. Using the average Keq you determined in lab (310.72), what should be the concentrations of the original Fe(NO3)3 and KSCN solutions? For the calibration plot, 0.10 mL increments of 0.00100 M KSCN are added to 4.00 mL of 0.200 M Fe(NO3)3, and for the equilibrium solutions, 0.50 mL increments of 0.00200 M KSCN are added to 4.00 mL of 0.00200 M Fe(NO3)3. endobj Because a large excess of Fe+3 is used, it is reasonable to assume that all of the SCN- is converted to FeSCN2+. /Length 8 0 R The thiocyanate ion acts as an isothiocyanate ligand to Fe3+, in other words, the iron binds to the nitrogen atom of the ligand not the sulfur atom.
