Iron 2 thiocyanate
WebPerturb the Fe3+ + SCN- ↔ FeSCN2+ equilibrium and use Le Chatelier's principle to predict which way the reaction will shift. WebIn the equilibrium lab, the equilibrium constant for the formation of iron (II) thiocyanate was spectroscopically determined. In a similar experiment, the formation constant of Co (SCN)2- was determined by mixing solutions of Ca (NO3)2 and KSCN and measuring the absorbance of the blue Co (SCN) - formed in the reaction.
