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 Iron-Thiocyanate Equilibrium Russel has given us a challenge that brings us to the concept of chemical equilibria and the iron thiocyanate reaction. ... mix, and observe.
