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 … WebThe equilibrium for the reaction of iron (III), Fe3+, with thiocyanate, SCN–, to yield the colored product, iron (III) thiocyanate, FeSCN2+, will be studied and its equilibrium constant determined spectroscopically using a Vernier Ocean Optics Spectrometer.
