Iron thiocyanate reaction
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 Thiocyanate (also known as rhodanide) is the anion [SCN] , a salt or an ester of thiocyanic acid. It is the conjugate base of thiocyanic acid. Common derivatives include the colourless salts potassium thiocyanate and sodium thiocyanate. Mercury(II) thiocyanate was formerly used in pyrotechnics. Thiocyanate is analogous to the cyanate ion, [OCN] , wherein oxygen is replaced …
