Reserve one as a reference. Add 0.1M Fe(NO3)3 solution to beaker #2. The color should become more intense as more complex is formed. Add 0.1M KSCN solution to beaker #3. The color should again become ...

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 ...
