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 ]. WebThe thiocyanate ion gives a deep red colour with iron(III) but should give virtually no colour with iron(II). However, unless it is very pure and freshly prepared, iron(II) will probably give a faint red colour due to the presence of some iron(III). Iron(III) oxidises iodide ions to iodine which gives the characteristic blue-black colour with ...
