Iron thiocyanate

WebSep 25, 2024 · Both the iron (III) compound and potassium thiocyanate are soluble in water. They break into their ions. The important players in the reaction are the Fe 3+ from the iron compound and the K + and SCN 2+ from the potassium thiocyanate. These ions form a red-colored iron (III) thiocyanate complex [KSCN=Fe (SCN)₃ ]. 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 …
