Iron 3+ reacts with excess thiocyanate and the latter reacts with excess of Flourine. The result is?

Dear student 

When you mix aqueous iron(III) nitrate and potassium thiocyanate together you get a red solution. Then if you add sodium fluoride, the red colour disappears
Fe(SCN)2+ ions are red, but FeF2+ ions are colourless.
Fe(III) (aq) is "hard" enough to prefer F- from SCN-.
