Als Thiocyanate (veraltet auch Rhodanide) werden die Salze und die Ester der unbeständigen Thiocyansäure (Rhodanwasserstoffsäure) HSCN bezeichnet. Der Name „Rhodanid“ leitet sich von griechisch rhodos für „rot“ ab, da Eisen(III)-thiocyanat eine tiefrote Farbe besitzt. Die Salze lassen sich am einfachsten durch Schmelzen der entsprechenden Cyanide mit Schwefel herstellen. rabbit ear cleaningWebEisenionen + Wasser + Thiocyanationen ——> Pentaquomonothiocyanatoeisen(III)-Ionen Ese .
