The thiocyanate anion, specifically, reacts with ferric salts to form a deep-red ferric thiocyanate complex: 6 SCN − + Fe 3+ → [Fe(SCN) 6] 3− Ammonium thiocyanate reacts with several metal ions including copper, silver, zinc, lead, and mercury, forming their thiocyanate precipitates, which may be extracted into organic solvents. Properties: Red, deliquesc crystals. 2 comments. The complex is produced as soon as ferric and thiocyanate solutions are mixed, and it is not possible by reducing the concentrations of the compo- nents to reduce the rate sufficiently to bring it into the range for kinetic study using conventional colorimeters or spectrophotometers. Ferric thiocyanate yielded the highest sensitivity with good accuracy and consistent absorbance measurements when the organic layer containing PS80/ferric thiocyanate complex was sampled after 1 h of wait time.
