Dilute solutions of Fe(NCS)2+ have their equilibrium positions shifted with the addition of Fe(NO3)3, KSCN, NaOH, and AgNO3. The ferric thiocyanate solution is blood red in color, and the intensity of ...

A series of precipitations and complex-ion-formations are performed in a single reaction vessel. Solutions ranging in concentration from 0.2 M to 2 M are suitable for this demonstration.
