WebApr 9, 2024 · Ferric ions are from ferric alum and thiocyanate ions are from ammonium thiocyanate. Additional information: The oxidation number of iron in ferric alum is +3. The oxidation number of iron in red coloured complex ferric thiocyanate is also +3. Thus, during complex formation reactions, there is no change in the oxidation number. Webprinting inks, paints, cosmetics (eye shadow), artist colors, carbon paper, and typewriter ribbons. The thiocyanate ion, SCN–, provides an excellent confirming test for the Fe3+ ion. The soluble, blood-red Fe(SCN) 3 complex is formed from the Fe3+ ion, while no complex is formed with the Fe2+ ion. Connecting to the National Standards grossinger gmc service
