Iron 3 thiocyanate

WebThe reducing medium precludes the colour reaction of thiocyanate with iron. Thiocyanate methods vary widely in sensitivity. The methods for determining Te, Fe(III), and Nb are highly sensitive, whereas those for U and Co are less sensitive. ... 3.2.2.3.7 Thiocyanate. The thiocyanate group has been studied in detail as a ligand for lanthanide ... In chemistry, iron(III) refers to the element iron in its +3 oxidation state. In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) denoted by Fe . The adjective ferric or the prefix ferri- is often used to specify such compounds — as in "ferric chloride" for iron(III) chloride, FeCl3. The adjective "ferrous" is us…
