Iron(III) Chloride and Potassium Thiocyanate reaction

  1. Mar 19, 2009 #1
    1. The problem statement, all variables and given/known data
    I need to know the reactants of an iron(III) chloride and potassium thiocyanate reaction.


    2. Relevant equations

    FeCl3(aq) + KSCN(aq) =??

    3. The attempt at a solution
    i think it is thiocyantoiron ion and potassium chloride, but this creates an unbalancable equation (FeCl3(aq) + KSCN(aq) = FeSCN + KCl)

    If you are looking for the "reactants", as you asked, then, you already named them. One of the PRODUCTS is a coordination complex. Look in the sections of your general chemistry textbook about coordination complexes. Three days to one week of study. Thiocyanate ion can form coordination complexes with several metal ions, including Fe ions. The ratio will not be 1 to 1 for the complex with SCN-.
