WebExperimentally determine the equilibrium constant, K, for the reaction of the iron (III) ion with the thiocyanate ion to form thiocyanoiron (III) ion. DISCUSSION Chemical reactions occur to reach a state of equilibrium. The equilibrium state can be characterized by quantitatively defining its equilibrium constant, K. 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 …
