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 ... WebIn this analysis the iron present in an iron tablet (dietary supplement) or a sample of food is extracted to form a solution containing Fe3+ (ferric) ions. To make the presence of these ions in solution visible, thiocyanate ions (SCN−) are added. These react with the Fe3+ ions to form a blood-red coloured complex: Fe3+ (aq) + SCN− (aq) → ...
