Iron thiocyanate reaction
WebThiocyanate (SCN-) is natural occurring in the human body that is secreted in the salivary glands. ¹ It is produced with the digestion of food and drugs used specifically to treat thyroid disorders or hypertension. High thiocyanate levels are indicative of cyanide poisoning² but could also be used to assess smoke exposure. WebCalculating the Equilibrium Constant for the Reaction of Iron (III) Nitrate with Sodium Thiocyanate The Reaction In your experiment, you will be reacting a solution containing colorless iron (III) ions with a solution containing thiocyanate, SCN-. The product produced, iron(III)thiocyanate ion (Fe(SCN) 2+) is yellow. Like any colored
