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 ...
